Be Professional With Your Tractor's Wiring!
First of all, an engine's ignition system is completely separate from its
electrical charging system. One has absolutely nothing to do with the other.
The power for a battery-powered ignition system comes from the battery while
cranking the engine to start it. Once it starts, the charging system takes
over, and while the engine is running at full governed speed, the charging
system recharges the battery, powers all electrical accessories, and powers
the battery-powered ignition system. A self-energizing magneto or
electronic/solid state ignition system do not depend on power from the battery
or charging system whatsoever.

When connecting the wires for an electrical system, don't just
make a connection by twisting bare wires together by hand and taping them
up. All this does is allow moisture between the wires and in time, lets corrosion
set in, causing a faulty connection. An older, experienced electrical engineer
once said: "Sometimes electrical problems are mechanical." Meaning a loose
or poor connection, or a faulty switch. Therefore, it's better to solder
the wires together, then tape them up with electrical tape or use appropriate
size
heat shrinkable tubing. Or for a "clean" and professional
look, use "crimp" style wire connectors to connect two wires together, or
connect a wire to a coil stud terminal or switch terminal. Use a
wire stripper / crimp connector tool to secure the crimp
connectors to the wire. Use a bench vise to crimp heavy connectors to battery
cables. Route the wiring along the inside of the frame in a safe and secure
manner, away from the spinning flywheel and clutch/driveshaft, moving levers,
and hot exhaust areas.
When removing and installing the engine in and out of a competition garden
pulling tractor (or any vehicle as far as this subject is concerned), for
whatever reason, install
male and female bullet or spade quick disconnect electrical
connectors (or any type of quick disconnect electrical connectors as
long as they're insulated from the engine and tractor/vehicle frame) in the
wiring circuit that's connected to the points, ignition module, coil, charging
system, or anything else that's wired to the engine, except for the heavy
battery cable that connects to the starter motor. The use of quick disconnect
electrical connectors allows for much easier and quicker disconnection of
the wires. Example: Before removing engine, the points cover will need to
be removed, then the wire needs to be disconnected from the points terminal
screw; and then remove the nuts from the ignition coil and then take a chance
on losing one of the small nuts. No tools are required for use with quick
disconnect electrical connectors either. No need to unscrew this, unbolt
that, just unplug the connectors by hand to remove the engine, and plug them
back together after reinstalling the engine. It's that simple. Many professional
race cars, funny cars, dragsters and NASCAR use this method to speed up the
quick engine rebuild or swap process in the pit area at the track on race
day. And most electronic appliances, such as computers, TVs, etc., used this
method for many years to simplify removing and installing circuit boards
and various components. Makes life a lot easier.
Always install either an
in-line round- or blade-type fuse holder,
panel-mount fuse holder,
blade-type automatic reset circuit breaker, or a
stud-type automatic reset circuit breaker in the primary
wire that's connected directly to the battery positive (+) post. (The
small wire that provides power to all electrical components.) An important
thing to remember is if using a universal automatic reset circuit breaker
in a competition garden pulling tractor, don't fasten it to any part of
the tractor! Instead, allow it to dangle free by the wires (hide it inside
the steering pedestal assembly), and wrap electrical tape around it so the
terminals won't short out against any bare metal part of the tractor. The
reason the circuit breaker shouldn't be mounted solid to any part of the
tractor is because at high RPM or wide open throttle, normal engine vibrations,
that's transferred throughout the entire tractor, will cause the bimetallic
strip (contact spring or "flapper") inside the circuit breaker to vibrate
(a lot) and become momentarily and erratically disconnected, causing the
engine to misfire badly and misfire or "cut out" while going down the track.
Having a fuse or circuit breaker (and ammeter/amp gauge
if the engine has a charging system) installed is very important to prevent
failure of electrical components. Because by the time you smell something
burning or see smoke, it may be too late.
To determine the size of fuse or circuit breaker, figure how many amps all
the connected electrical accessories draw, then use a fuse or circuit breaker
with an amp rating slightly higher to prevent the fuse from burning out or
the circuit breaker from overloading and popping. If a short occurs, the
fuse will need to be replaced and the circuit breaker will automatically
reset itself.
Also, it's a good idea to install
a main disconnect/cutoff switch to kill electric
power to everything on the equipment. This is useful when equipment is not
used for a period of time to prevent a slow drain on the battery, prevent
short circuits when performing electrical service on equipment, or for a
pulling tractor to prevent accidental starts or to prevent sabotage at the
pull sites from disgruntled pullers.
How Lead Acid Batteries Good Bad - (Added
2/6/21) Top of Page
Once the lead (a soft heavy toxic malleable metallic element) on the plates
of one cell falls off and builds up on the bottom of the battery (this usually
happens with a cell on the positive (+) post) , it will short out that cell,
causing a dead cell. There is no fix for this whatsoever. The only solution
is to purchase a new battery and keep it fully charged. Or when a battery
sits too long with no charge, the activity of the acid will become neutralized,
and become like water. If you're lucky, it can be reactivated with a trickle
charger. Otherwise, the battery is bad and needs to be replaced with a new
one. Or, the water-like acid can be drained and replaced with fresh acid
& "maybe" the battery can be fully charged for activation again. Or,
if the charging system continually charge the battery at full amperage due
to a faulty voltage regulator or voltage rectifier/regulator, this will "burn
up" the acid and the lead plates, causing a bad battery. The only solution
for this is install a new voltage regulator or voltage rectifier/regulator
and replace the battery with a new one.
Testing the Starting Circuit -
To test the starting circuit
on virtually any lawn, garden or larger tractor, first, make sure that the
battery is fully charged and in good condition, and the cables have a good
connection. Use a
Battery Load Tester to determine the condition of the battery.
If the battery is satisfactory and the connections are good, using either
a screwdriver, metal rod or jumper wire, energize the starter solenoid/relay
by connecting the large terminal on the solenoid/relay where the heavy battery
wire connects, to the small "S" terminal on the solenoid/relay where the
starter switch connects. The starter should spin and crank the engine. If
it doesn't, then the solenoid/relay is defective.
If the starter switch will not crank the engine, to test the starting
circuit, use a fully charged
portable battery booster/jumper or a 12 volt automotive
battery with minimum 6 gauge x 2 foot length jumper wires and heavy duty
clamps. Clamp the battery positive (+) lead directly to the terminal on the
starter motor, and temporarily touch the battery negative () lead to
the engine/chassis ground. If the engine cranks over with no hesitation,
then the starter motor is in good condition, and the problem is either the
solenoid/relay, starter switch or wiring. But if it just spins without engaging
into the flywheel, then the gear teeth are worn or the gear is binding on
the spiral of the armature shaft. But if the starter motor does nothing at
all or turns slow, then either the brushes are worn, the commutator is dirty
and needs cleaning, and/or the armature shaft bushings also needs cleaning
and lubricating, or the windings are burned up. Or, the engine itself could
be causing drag on the starter (turn slow) due to either too heavy/thick
(wrong viscosity) crankcase oil in cold weather, damage inside the engine,
or a parasitic accessory (PTO clutch, etc.) may be too tight, binding or
worn, preventing the engine from cranking normally. And never assume that
a starter motor is in good condition. When in doubt, it should be disassembled
to verify that the windings are in fact burned up, the brushes are worn,
or if the magnet(s) are broken. Because like the old saying goes: "Assumption
is the mother of all foul ups."  |
How to Connect the Wires on the Starter Solenoid/Relay -
If a solenoid/relay have just one 3/16" terminal, the solenoid/relay is grounded
internally through the mounting bracket. But if a solenoid/relay has two
unmarked 3/16" terminals, the solenoid/relay is grounded externally through
one of the 3/16" terminals. It doesn't matter which terminal is used. Connect
one small terminal to the starter switch and the other to the engine/chassis
ground (negative () battery post). When electric current is applied,
the two small terminals energizes a magnetic field within the solenoid/relay
so the plunger that's connected to a brass disc within can make contact across
the two larger terminals to complete the circuit from the battery positive
(+) post to the starter motor. On most larger solenoid/relays having two
marked 3/16" terminals, the one that's marked with an "S" [Start]
connects to the starter switch. It energizes the solenoid/relay so power
can be connected from the battery through the solenoid/relay to the starter.
With points and condenser/capacitor ignition, the "I" [Ignition] terminal
on the solenoid/relay (not present on all solenoids/relays) by-pass the ballast
resistor or resistor wire for points/condenser ignition, or connects to the
Chrysler or Ford electronic ignition control module to give the coil a stronger
spark for faster engine start up. There's no need to use the "I" if
the coil has an internal resistor or with crank trigger ignition. The
solenoid/relay is grounded through the mounting bracket.
A solenoid/relay (sometimes referred to as an "electric switch" or "relay")
eliminates the use of a high amperage momentary push button starter switch
and heavy wiring throughout the starting circuit.
How A Starter Solenoid/Relay Becomes Defective -
When the engine that uses a
starter solenoid/relay cranks over right away upon the turn of the ignition
key or the push of the start button (and the engine starts right up), but
every now and then when the key is turned or the button is pushed, either
nothing happens or there's a constant clicking sound. What's happening is,
as the round brass contact disc inside the solenoid rotates slightly upon
each activation (magnetic engagement) of the solenoid/relay, the edge of
the disc is either burned away, or the brass contact lug on one or the other
big terminal (where the battery cable and starter motor cable connects) is
burned away. When the metal gets burned away on either part (which is
inevitable), neither will make contact to complete the circuit. If the disc
and/or lugs aren't totally burned away, when attempting to crank the engine
(turning the key back and forth, or push the button again and again), eventually,
a good spot on the disc makes contact with the lugs, and the starter spins.
How to Test a Starter Solenoid/Relay -
Tools needed are -
analog or
digital multimeter, fully charged 12 volt battery and four
jumper wires with clips. The test is performed as follows -
-
Connect the battery negative () post to the mounting base on the
solenoid/relay
-
Set the multimeter on ohms resistance and connect the leads of the multimeter
to the two big terminals on the solenoid/relay.
-
Connect a jumper wire from the battery positive (+) post to the small [S]
terminal on the solenoid/relay.
-
The solenoid/relay should click, and the ohm meter should show a full scale
reading.
-
If the solenoid/relay don't click, then it's defective. Or if it does click
with no ohms reading between the two big terminals, the solenoid/relay is
defective.
To connect the wires on a starter solenoid/relay to energize a starter
motor -
-
Ground the solenoid/relay to the engine/chassis ground or negative ()
battery post.
-
Connect an 8 AWG (American Wire Gauge) battery cable from one of the big
terminals on the solenoid/relay to the battery positive (+) post.
-
Connect an 8 AWG battery cable from the other big terminal on the solenoid/relay
to the starter motor.
-
Connect the small terminal on the solenoid/relay with a 16 AWG wire to one
of the wires or terminals on a push-button starter switch.
-
Connect another 16 AWG wire from the push-button starter switch to the battery
positive (+) post.
-
When the button is pushed, the solenoid/relay should click, sending an electric
current through the two big terminals to complete the circuit for the starter
motor and energize the starter motor.
In some cases, it's not the starter motor who is the culprit of not being
able to crank a big cubic inch or high compression engine. Sometimes the
ignition timing can be so advanced, the starter tries to crank the engine
to start it, but the advanced spark causes the crankshaft to "kick back."
Sometimes if the kick-back is severe enough, the armature in a direct-drive
starter motor will bend or break. To fix this problem and prevent damage
to the starter, use the
same starting technique
as the Tecumseh cast iron engine with the crank trigger ignition. Install
two separate switches - one being a momentary push button to crank the engine
and the other being an ordinary Grounded OFF/ON Toggle Switch. To make this
work, first crank the engine over with the momentary push button switch,
choke it, then flip the [ignition] switch to "put the spark to it" (power
up the ignition). This should allow it to start easily and effortlessly every
time.
If an engine is slow at cranking over or will barely crank over, then the
first thing to check is the condition of the engine. If it cranks over somewhat
easy by hand, then it's probably OK. The next thing to check is the condition
of the battery. Use a
Battery Load Tester to determine the condition of the battery.
If it tests good, then check the wire connections and start solenoid/relay
(if equipped). If they're OK, then the lat thing to check is the condition
of the starter motor. Disassemble it and observe the condition of the wire
windings on the armature. If they're dark brown in color and have a burnt
smell, then the motor is burned up. But if the windings are light brown or
"bronze" in color, then they're in good condition. Clean the commutator (the
part on the armature where the brushes make contact) and shaft where the
bushings make contact with emery cloth in a metal lathe.
IMPORTANT - If you don't feel comfortable using
a metal lathe, please consult a professional and experienced machinist with
a lathe. Before reassembling the starter, lightly lubricate
the bushings with motor oil. If the engine still won't crank over easy, then
either the ignition timing is too advanced or the compression release isn't
working. Too much valve clearances could also cause hard cranking.
Some starter motors are American made, some are imported. But most nowadays
are made of excellent quality and manufactured to exceed OEM specifications.
As a matter of fact, virtually all OEM Kohler starters are made in China,
so are most of their other engine parts. Kohler owns two factories in China.

Be gentle when handling a starter motor, especially
one with permanent magnets. Never abuse it by dropping it on the floor or
hitting it with a heavy metal object, such as a hammer! Doing this could,
or most likely will, break the fragile ceramic magnets inside and render
it totally useless. (I've
had some customers strike a starter motor with a hammer, thinking this will
fix it when it fails to operate. No joke.)

Most quality-made starter motors
are designed to last the life of the engine. Therefore, if a good starter
burns up prematurely, then this means that it has cranked the engine for
too long at one time. All starters are actually 6 volt motors operating on
12 volts. This is what gives them so much torque to crank the engine so fast
and with ease. So if a starter motor is spun too long (longer than 2 minutes),
the excess voltage will burn up the wire windings in the starter. The longer
it's spun, the hotter it will get, which causes the windings to get very
hot, which causes the insulating/separating varnish coating on the windings
to melt. When the coating melts, the windings make contact with each other
and become shorted out, and you have a burned up starter on your hands. That's
why most owner's and repair manuals say to never crank an engine longer than
2 minutes at a time without allowing adequate time for the starter to cool
before cranking it again. (If an engine won't start within 2 minutes of cranking,
then it obviously needs a major tune-up or repair!) And unlike
most automotive starters, which are in big demand, nobody rebuilds (rewinds)
Kohler starter motors.
There's three things that can cause a good starter motor to burn up -
-
Continuously cranking an engine for more than 3 minutes at one time will
likely to burn up a good starter motor. They're 6 volt motors operating on
12 volts. This is what gives them extra cranking power.
-
Another thing that can burn up a good starter motor is using an older OEM
Kohler starter. They're low torque compared to most new imported starters,
which high torque. Most engines cranks over easier and starts quicker with
a high torque starter motor.
-
Using a camshaft without the compression release usually won't burn up the
starter. Sometimes the starter just isn't capable of cranking the engine
due to the high compression.
If you
would like to have a starter motor to crank your engine without hesitation,
you'd be better off purchasing a new one or one that's been professionally
rebuilt. Never put full trust in a used electric starter to crank your engine
unless your receive an unconditional guarantee that it's good. Otherwise,
there's a chance that it's either 90% wore out, burned up or the magnets
are broken, and the owner is just trying to sell "junk" to another person.
A starter may look nice and clean on the outside, but it's what's on the
inside that matters. Some of these questionable starters are sold "AS IS"
on places like eBay. So remember these words... "BUYER BEWARE!" By the way
- I'm not trying to sell you a new starter here, I'm only informing you of
the facts.
How to Reassemble a Kohler Starter Motor -
Before reassembling a Kohler
starter motor, first, a brush holder tool must be fabricated from sheet metal
to depress and retain the brushes in their cavities before the end cap can
be reinstalled onto the starter housing. Without this tool, it is nearly
impossible to install the end cap with the brushes depressed.
To properly install the end cap on the housing, align the projected tang
inside the housing with the notch inside the end cap so the bolt holes will
be aligned and so the terminal will be in the correct position. Install the
bolts, then the brush holder tool can be pulled out and the brushes will
snap against the commutator, and then tighten the bolts to 15 in. lb.
Always Use a High Quality and Fully Charged Battery to Crank a Competition
Pulling Engine!
First of all, to test the condition
of a battery, use a professional
Battery Load Tester as shown to the right ->. Avoid
purchasing a "cheapie" made-in-China load tester. These do not work at all!
Anyway, to use a load tester, remember that when testing a [high-amperage]
automotive battery, use the higher amp scale on the display/meter, and when
testing a low-amperage battery, such as for a riding mower, lawn & garden
tractor, small motorized vehicle, ATV/UTV, motorcycle, etc., use the lower
amp scale on the display/meter. And if possible, fully charge the battery
(preferably overnight) with a
battery charger. When the battery is fully charged, disconnect
the battery charger, and connect the clamps on the load tester to the respective
battery posts (RED > positive
(+), BLACK > negative ()),
hold the Load Switch ON for 10 seconds while observing the display/meter.
If the display needle is in the
GREEN (GOOD/OK) area,
the battery is in usable condition. But if the display is in the
YELLOW or
RED (BAD/WEAK) area, then
the battery is defective.
Most [stock] single cylinder pulling engines with the automatic compression
release (ACR) in working condition with a high torque starter motor and a
minimum 350 CCA lawn & garden battery should crank over and start with
no problems. But a pulling engine without the ACR may hesitate when the piston
comes up on the compression while being cranked. Therefore, it'll be a good
ideal to use a high torque starter motor along with a high amp battery, such
as a small
12 volt 35AH (Amp Hour) sealed lead acid (SLA) battery,
a minimum
350 CCA lawn & garden battery, or better yet, a small
12 volt automotive battery (if it will fit in the battery box). The 12 volt
35AH battery packs a lot of punch (cranking power) and it's vibration-resistant,
making ideal for use in a competition garden pulling tractor.
No professional puller that I know of have a charging system incorporated
with the engine on their pulling tractor. A charging system will rob the
running engine of valuable power while it's recharging the battery. Therefore,
to maintain a fully charged battery, a
battery charger will need to be used when the tractor is
not in use or in storage.
Widening a Narrow-Frame Cub Cadet for use with a
Large Flywheel and Gear Starter Motor - Top of
Page

The frame rails on all narrow frame IH Cub Cadets (models 70, 71, 72, 73,
100, 102, 104, 105, 106, 107, 122, 123, 124, 125, 126, 127 and 147) are too
narrow for use with any K241-K361 Kohler engine with the larger diameter
(9-1/2") flywheel (the small flywheel is 8" in diameter.), bearing plate,
shroud and upper mount gear starter (mounting bolts are below the starter
motor). These larger parts, including the charging stator (alternator charging
ring under the flywheel), can be installed on any K241-K361 Kohler engine
with no problems. Click or
tap here for details on how to widen the frame rails. |
The upper mount gear starter (mounting bolts are below the starter motor)can't
be installed on the very early K241 engine blocks because there's no indentation
in the block just above the starter's mounting holes. These blocks were designed
for the starter/generator only. |
Parts needed to convert virtually any small gas engine to electric gear
start -
-
12 volt battery and starter motor, both capable of cranking the engine
effectively.
-
Starter solenoid/relay or high amperage starter switch.
-
Charging system (to recharge and maintain battery voltage and power electrical
accessories). Use either a flywheel w/ring gear with internal ring
of magnets, stator with an electronic/solid state voltage rectifier/regulator
[if stator produces more than 3 amps]; an automotive-type generator/alternator
with voltage regulator/rectifier; or a remote
battery charger
|
-
16 AWG wiring to connect solenoid/relay to starter switch and connect charging
system.
-
8 AWG battery cable to connect between starter and solenoid/relay or high
amperage starter switch, and between solenoid/relay or high amperage starter
switch and battery.
|
Parts needed to convert a Kohler K-series engine with a starter/generator
to a gear starter -
-
Large diameter (9-1/2") flywheel with a starter ring gear.
-
Large bearing plate that's designed for a gear starter and charging stator.
-
Flywheel shroud for bearing plate shown above
È (for either an upper mount gear starter
[mounting bolts are below the starter motor] or lower mount gear starter
[mounting bolts are above the starter motor]).
|
-
Gear starter (OEM type). (Lower mount for K141, K160/K161 and K181 engines,
and lower mount on the K241-K361 engines if the gas tank is in the way -
not for Cub Cadets. Upper mount only on K241-K361 engines for Cub Cadets.)
-
Starter solenoid/relay (if your particular tractor require one).
-
Charging stator and voltage rectifier.

Parts needed to convert a stand-alone Kohler K-series [welder or generator]
engine models K241, K301, K321 or K341 with a manual recoil or rope starter
to an electric gear starter system - (Added 9/13/18) [Top
of Page]
Parts off of a Kohler Magnum engine model M10, M12, M14 or M16 can be
used. Parts needed are - flywheel w/plastic fan, starter motor, bearing plate,
solid state ignition coil/module w/mounting screws and inner air baffle.
These parts will interchange between the K241, K301, K321 and K341 engines.
Also, these parts are hard to find nowadays because Kohler didn't make many
Magnum single cylinder engines. The best to find these parts is on eBay,
local small engine repair shops/salvage yards, Craigslist, visit antique/vintage
swap meets/shows or search Google. |
Depending on battery drainage and need for recharging, to be precise, and
with the engine running at 3,600 RPM, the generator part of the starter/generator
unit or alternator stator uses about 3/8hp (of engine power) when it recharges
a fully discharged battery at full 15 amps; about 5/8hp at full 20 amps;
and about 7/8hp at full 30 amps. But if the battery doesn't need much recharging,
the charging system draws less hp from the engine. I know this small amount
isn't much, but every hp counts in competitive pulling. So to reserve this
power for pulling, disconnect the generator or alternator from charging the
battery (and powering other electrical accessories as well) simply by splitting
the wire that connects to the FIELD terminal (the smaller wire and terminal)
on a starter/generator unit and splitting the wire that connects to the center
terminal on the voltage rectifier/regular of an alternator system. Then connect
an ordinary Grounded OFF/ON Toggle Switch in that wire or circuit to turn
off and on the charging current. And it'll be best not to spin the
starter/generator when pulling. Being it has ball bearings, the excessive
spinning won't hurt it. But being the V-belt causes drag, depending on belt
tension, it can use up to 2hp of engine power just to spin it. This is also
power that can be put to the rear tires for pulling. Besides, wouldn't it
be better to spin the tires than the starter/generator? So to disengage the
starter/generator belt, install threaded studs with locknuts on the
starter/generator bracket and install a heavy spring on the starter/generator
so it'll remain close to the engine. To crank the engine, install the belt
on the pulleys, then pull out on the starter/generator with a fabricated
handle to tighten the belt. After the engine starts, release the
starter/generator and flip the belt off. But use caution doing this for an
obvious reason!

High Quality Digital
Tachometer/Proximity Sensor Kits. A tachometer is required in setting
the correct engine RPM, which is normally 3,200 or 3,600 RPM (depending on
type of carburetor), to prevent from over-revving and possible damage to
the engine or dangerous flywheel explosion. Choice of a
RED or
BLUE numeric display. Will work with
most small engines or multi-cylinder automotive engines, gas or diesel. The
great thing about this type of tachometer is that it needs no setup or
programming. It displays accurate RPM as soon as the engine cranks over to
start. Displays up to 9,999 RPM. Very accurate. Tachometer returns to zero
[0000] when engine is shut down. Can be used for lawn & garden equipment
or competition pulling engines. Designed to be permanently mounted to monitor
engine RPM at all times. Tachometer can be in-dash or panel-mounted. This
precision digital tachometer operates with external power and on the same
principle as my
flywheel- or
crank-trigger ignition systems with a proximity sensor to detect the
target, which can be a small ferrous steel screw or pin, or magnet in a rotating
disc on the crankshaft or on/in flywheel. Operates totally independent of
the ignition system, or can be used with crank trigger ignition with the
same proximity sensor. Sensor is capable of powering this digital tachometer
and crank-trigger ignition module at the same time, with the exception of
using the Dynatek Dyna S or PerTronix Ignitor modules. This tachometer must
be wired separately or wiring can be incorporated with my crank-trigger ignition
system that use a proximity sensor. A sturdy steel or aluminum bracket will
need to be fabricated by customer to mount the sensor in close proximity
of the detector/trigger target. Set air gap/clearance at .010"-.188". Tachometer
works with 8-24 volts DC, proximity sensor works with 6-36 volts DC. Dimensions
for mounting hole for tachometer: 3" wide x 1-17/32" wide. Tachometer measures
1" in depth. Dimensions of proximity sensor: 15/32" diameter x 1-3/8" thread
length. Wiring Instructions: #1 wire on tachometer connects to brown wire
on proximity sensor and ignition switch (12 volt power), #2 wire on tachometer
connects to blue wire on proximity sensor and engine/chassis ground (which
connects to the negative () battery post), and #5 wire on tachometer
connects to black wire on (either) proximity sensor. Wires #3 and #4 connects
to nothing. Wiring is the same for the hall effect and inductive proximity
sensors. Some proximity sensors have an LED (Light Emitting Diode) on the
rear of unit. If the proximity sensor is wired incorrectly, the LED will
illuminate within the target.

Superior Quality, High Velocity 12 Volt Auxiliary Engine Cooling Fan. Use
an electric fan to cool a competition garden tractor pulling engine with
a steel flywheel and no cooling fins. Unlike fan blades that's fastened to
the flywheel, an electric fan will not produce drag and rob power from the
engine. Install fan with motor forward of blades (for maximum velocity) aimed
toward exhaust area of engine. Fasten fan housing on a sturdy angle steel
support brace with 1/4" bolts, flat washers, lock washers and nuts, in front
of engine or behind grille in a garden tractor. See photos to the right and
below. No need to mount fan housing on rubber grommets; these will serve
no purpose whatsoever. Fan motor is 100% secured and reinforced to plastic
housing to withstand severe engine vibrations to prevent motor from loosening
and become inoperable when pulling. Distinctive feature by A-1 Miller's.
Draws 2.6 amps, produces 145 CFM. Measures 3" diameter and 5" length.
IMPORTANT: It's recommended that the fan not
be run while pulling because due to normal engine vibration, the brush holders
inside motor could break. Turn fan on ONLY between pull-offs or when tuning
engine. $40.00 each, plus shipping & handling.

High Torque
Gear Starter Motors. Fits Kohler engine models K141, K161 and K181. 12 volt
negative ground. All starter motors are high torque nowadays. They have 20%
more wire windings than the early OEM Kohler starter, giving it 20% more
cranking power. Cranks engine about twice as fast and draws less amps than
an ordinary starter; a smaller battery can be used.
But with a
broken compression release, a direct-drive high torque starter may not be
able to crank the engine. It'll be best to adjust the valve clearances, repair
the compression release mechanism or replace the cam with a working compression
release. FYI - The aftermarket starter motors I
sell are the same as OEM Kohler starters. Kohler just place a big markup
on theirs because it comes in a box with the Kohler name on it and the starter
has the Kohler name stamped on it.

Most
quality-made starter motors are designed to last the life of the engine.
Therefore, if a good starter burns up prematurely, then this means that it
has cranked the engine for too long at one time. All starters are actually
6 volt motors operating on 12 volts. This is what gives them so much torque
to crank the engine so fast and with ease. So if a starter motor is spun
too long (longer than 2 minutes), the excess voltage will burn up the wire
windings in the starter. The longer it's spun, the hotter it will get, which
causes the windings to get very hot, which causes the insulating/separating
varnish coating on the windings to melt. When the coating melts, the windings
make contact with each other and become shorted out, and you have a burned
up starter on your hands. That's why most owner's and repair manuals say
to never crank an engine longer than 2 minutes at a time without allowing
adequate time for the starter to cool before cranking it again. (If an engine
won't start within 2 minutes of cranking, then it obviously needs a major
tune-up or repair!) |
10 and 13 Tooth
Upper Mount High Torque Gear Starter Motors. (Mounting bolts are below starter
motor.) Fits certain Kohler K-series engine models K241, K301, K321, K341
and K361. 12 volt negative ground. All new starter motors are high torque
nowadays. They have 20% more wire windings than the early OEM Kohler starter,
giving it 20% more cranking power. Cranks engine about twice as fast and
draws less amps than an ordinary starter; a smaller battery can be used.
In addition to the extra windings, the 10 tooth starter gear gives this starter
extra torque so it'll crank the engine with less effort. The 10 tooth starter
provides 13% more cranking torque than the 13 tooth starter, and the 13 tooth
starter cranks the engine over 30% faster than the 10 tooth starter. The
13 tooth starter is best to be used with working compression release.
But with a
broken compression release, a direct-drive high torque starter may not be
able to crank the engine. It'll be best to adjust the valve clearances, repair
the compression release mechanism or replace the cam with a working compression
release. FYI - The 10 tooth starter cannot be used
in place of the 13 tooth starter, but the 13 tooth starter can be used in
place of the 10 tooth starter by shimming/spacing the starter away from the
engine block with an ordinary flat washer on each mounting
bolt.
And the aftermarket starter motors I sell are the same as
OEM Kohler starters. Kohler just place a big markup on theirs because it
comes in a box with the Kohler name on it and the starter has the Kohler
name stamped on it. NOTE: The early K241 and K301 engines must have
a curved indentation above the two bolt holes on the right side of the block
when facing the flywheel to install the upper mount starter motor.

Universal
Analog 10 Amp and 20 Amp Ammeter / Amp Gauge Kits. Gauges registers up
to 10 or 20 amps of charge, depending on total output amperage of stator
or alternator. Install these gauges to know exactly what the charging system
on your engine is doing. Having an ammeter/amp gauge installed is very important
in monitoring the charging system to prevent premature failure of electrical
components. By the time you smell something burning or see smoke, it may
be too late. If the charging system continues to charge on the plus (+) side
with no gradual moving back of the needle to zero on the gauge (if installed)
while the engine is running at full governed speed, due to a faulty voltage
rectifier/regulator, this will send too much voltage to the battery, which
could eventually burn up the cells in the battery, or burn up the primary
windings in the ignition coil. Overcharging of the electrical system could
also burn up the electronic ignition control module/unit
(crank-trigger and flywheel-trigger), burn
out light bulbs, electric PTO clutch or any other electrical accessories.
As battery becomes fully charged, needle slowly moves from positive side
(+) to zero (0). Needle will stay on negative side () if no charge
goes to the battery. Or gauge will not show any charge at all if charging
system is not working. Easy 2-wire connections. Connect the positive (+)
terminal on back of gauge to the battery positive (+) post, and connect the
negative () terminal on back of gauge to the wire going to the ignition
switch that provides power to everything. If the
wires/connections are reversed, and if the charging system is in good working
condition, the gauge will show discharge () instead of charge (+).
Use minimum #12 gauge (AWG) stranded wire. Non-lighted gauges. Each require
a 2" diameter mounting hole and comes with mounting clamp and nuts.

New 15 Amp Analog
Voltage Regulator for 12 Volt Starter/Generators. If the charging system
continues to charge with no gradual moving back of the needle to zero on
an analog ammeter/amp gauge (if installed) while the
engine is running, this will put too much voltage throughout the entire
electrical system, which could eventually burn up the ignition coil, battery,
burn out light bulbs, burn up the electric PTO clutch, burn up the electronic
ignition control module (crank trigger ignition)
and burn up the any other electrical components. With the terminals facing
you, they read: L = Lights | Bat = Battery | F = Field, A = Armature (on
the bottom). L connects to the Lights (if equipped); Bat connects to the
ignition switch, which connects to the battery positive (+) post; F connects
to the Field terminal on the starter/generator; and A connects to the Armature
terminal on the starter/generator. The frame of the regulator must be securely
grounded to the engine, tractor or equipment through the mounting bolts,
which connects to the battery negative () post. NOTE: Cannot be
substituted for use with the alternator/stator charging system.

  Two
Wire Rectifier Diodes. The 3- and 4-amp diodes can be used in a 12 volt
non-regulated small engine alternator/stator charging system to convert
alternating current (AC) to direct current (DC) to recharge the battery and/or
power low-amperage DC electrical accessories, such as LED lights, small electric
motors, etc. A diode is not required for
filament light bulbs, fluorescent and/or an electric PTO
clutch. The 1 amp diode can be used on an engine with a small charging coil
next to the magneto ignition coil on the stator to energize the field windings

FYI - Briggs & Stratton engines have either one or two OEM alternator
stators and they are joined together in two half circles under the flywheel.
Some engines only come with one half stator. Each half produce 3 amps of
power & 14 volts @ 3,600 RPM. If an engine comes with two stators joined
together, one half produces AC, which is used to power the lights and electric
PTO clutch. And the other half also produce AC, but is connected to a minimum
3 amp/14 volt diode, which is used to only recharge the battery. Under normal
yard use, 3 amps is not enough to overcharge and burn up the battery. If
both stator halves are wired together from the factory (as they are on certain
engines), they will produce 6 amps of AC power and a 6 amp electronic/solid
state voltage rectifier/regulator is used to power the lights, electric PTO
clutch and recharge the battery. |
Electronic/Solid
State Voltage Rectifier/Regulator for Old Style 10 Amp Output 12 Volt Alternator
Charging Stators (listed below). If the charging system continues to generate
full charge with no gradual moving back of the needle to zero on an analog
ammeter/amp gauge (if installed) while the engine
is running, the excessive overcharging may eventually burn out the primary
windings in the ignition coil, burn up the electronic ignition control module
(crank trigger), burn up the battery, burn
out light bulbs, electric PTO clutch, and any other electrical accessories.
These will also work with virtually any 15 or 20 amp small engine
alternator/stator charging system. Orientation of terminals are "three in
a row" (AC | BAT+ | AC). NOTE: Cannot be substituted for use with the
starter/generator charging system. FYI: After many years of use and
for reasons unknown (even to me), the old-style 10 amp charging system is
notorious for generating very few amps, about 3 amps more or less maximum
at full governed engine speed, and I have no idea why. I believe this is
why the 10 amp stator was a short-lived item that was discontinued from Kohler
and replaced with the more reliable 15 or 20 amp stator charging system,
which works much better and is still in use on many makes and models of small
engines today. So if your engine has the 10 amp charging system and it only
generates a few amps, it may need to be upgraded with the new-style 15 or
20 charging system.

Electronic/Solid
State Voltage Rectifiers/Regulators for New-Style 15/20 Amp Output 12 Volt
Alternator/Stator Charging Stators (listed below). If the charging system
continues to charge with no gradual moving back of the needle to zero on
an analog ammeter/amp gauge (if installed) while the
engine is running, this will put too much voltage throughout the entire
electrical system, which could eventually burn up the ignition coil, battery,
burn out light bulbs, burn up the electric PTO clutch, burn up the electronic
ignition control module (crank trigger ignition)
and burn up the any other electrical components. Each listed below work the
same. These voltage rectifier/regulators are small, compact and have the
same mounting hole spacing, and fit many 8 thru 24hp Kohler engine models
with a 15 or 20 amp alternator/stator charging stator under the flywheel.
For various makes and models of small engines with a 30 amp stator, instead
of using a 30 amp NOS (and high dollar) replacement voltage rectifier/regulator
(discontinued Kohler part # 277063-S), two 15/20 amp voltage
rectifiers/regulators wired in parallel can be used. Each listed below mounts
in the rectangular hole in the Kohler flywheel shroud with ribs facing the
flywheel for better cooling of the unit. If it's mounted elsewhere with no
cool air blowing over it, it could overheat and prematurely burn up. These
can be substituted for use on virtually any 15 or 20 amp garden tractor,

Use with flywheel having six internal ceramic magnets, which will produce
15 or 20 amps at 3,600 RPM. If used with a flywheel having three
factory-installed magnets that's spaced equally apart (rare), the stator
will only produce 7.5 amps at 3,600 RPM. The 3 wire stator that's designed
for Breakerless Ignition produces 15 amps at 3,600 RPM, and the 2 wire stator
that's not designed for Breakerless Ignition produces 20 amps at 3,600 RPM.
The 15 amp stator should work great for most applications, being the electrical
accessories on most garden tractors, small motorized vehicles, and small
engine equipment, including recharging the battery, require less than 15
amps of power. Dimensions of each stator: 5-1/2" O.D. x 2-3/4" I.D. x 2-1/4"

How to Fix a Briggs & Stratton Opposed Twin Cylinder Engine Starter
Motor When the Gear Teeth Will Not Fully Engage in the Flywheel Ring Gear
Teeth -
Information on the Kohler (Including Most
Other Makes and Models of Small Engines) Charging Systems -
[Top of Page]
First of all, the battery's only purpose in virtually any vehicle is to provide
power to the starter motor to crank the engine and power electrical accessories
when the engine isn't running. When the engine is running, and while the
battery is being recharged, the alternator/stator or generator then powers
the electrical accessories through the electronic/solid state voltage
rectifier/regulator. With the engine running, and with a good working charging
system, the battery has nothing to do with powering the electrical accessories.
The ignition system also have nothing to do with the charging system. It's
only purpose is to provide spark to the engine. The charging system and ignition
system are two totally separate systems. One has nothing to do with the other,
other than the charging system provides power to the battery-powered ignition
system. A magneto or electronic/solid state ignition is a stand-alone system.
It does not depend on the battery or charging system whatsoever.
The Generator/Starter Charging System -


The voltage-producing
generating part of a starter/generator (or just the generator unit in an
older automobile or heavy equipment machinery) produces DC (direct current)
electricity. These are belt-driven and require a mechanical voltage regulator
to regulate the charge to the battery and power electrical accessories (such
as lights, electric PTO clutch, etc.) at the same time. The faster the engine
runs, the more voltage and amperage the generator produces. And unlike a
belt-driven automotive-type alternator, the generator is self-energizing.
It will produce its own electricity when spun fast enough. A charged battery
is not required.
Although bulky, heavy and uses more space next to the engine, this system
is reliable, but produce little- to no-charge at low idle speeds and are
considered obsolete by today's standards. Also, this system require more
horsepower from the engine than the alternator/stator system while recharging
the battery and/or under a heavy electrical load.
I don't rebuild starter/generators. A business that specializes in rebuilding
automotive starters, alternators and generators can also rebuild
starter/generators. Or, you can purchase a new or used starter/generator
off of eBay.
On certain starter/generators and for identification purposes only, the
"A"
(Armature) terminal may be bigger (#12) than the "F"
(Field)
terminal (#10). IMPORTANT - If the wires for the Armature
and Field are connected to the wrong terminals on the starter/generator (reversed
connection), the field windings inside will burn up instantly (lots of smoke)
upon engine start up! Anyway, the correct wiring connections for the
starter/generator is as follows...
-
Two wires connects to the "A"
terminal on the starter/generator:
-
A minimum 8 AWG wire connects from the "A" terminal on the starter/generator
to one of the big post on the heavy duty push-button starter switch or starter
solenoid/relay. This connection cranks over the engine. (The other big
post on the heavy duty push-button starter switch or starter solenoid/relay
connects to the battery positive (+) post.)
-
A 14 AWG wire connects from the "A" terminal on the starter/generator to
the "A" terminal on the voltage regulator. (This wire provides electricity
to recharge the battery and power electrical accessories.)
-
A 14 AWG wire connects from the "F" terminal on the starter/generator to
the "F" terminal on the voltage regulator. (This is the Field windings
energizing wire.)
-
Mounting base of voltage regulator must be grounded to starter/generator,
engine/chassis ground (negative () battery post).
A starter/generator can be adapted to virtually any horizontal shaft or vertical
shaft small engine with a fabricated mounting bracket and a slotted adjusting
brace to tighten the belt. The starter/generator will need to be installed
opposite the carburetor side of the block. They come in two rotations: clockwise
and counter-clockwise. Starter/generators that spin clockwise came on older
Wheel Horse, Sears Suburban, Bolens, or any engine that's started from the
flywheel end. A counter-clockwise starter/generator came mostly on older
Cub Cadets, or any engine that's started from the PTO end. A clockwise rotation
starter/generator will need to be used if it's driven from the flywheel end.
But if it's driven from the PTO end, it will need to be a counter-clockwise
rotation starter/generator. If the wrong starter/generator is used, it'll
crank the engine opposite of normal rotation, and not recharge the battery.
If a starter/generator is belt-driven by an engine and used only as a generator
to charge up a vehicle's battery and/or power 12 volt appliances or lights,
the heavy battery cable won't need to be used. And there's about a 3:1 ratio
between the starter/generator and engine. This means the starter/generator
spins about 3 times faster than the engine. So the pulley on the engine will
need to be about 3 times bigger than the pulley on the starter/generator
to adequately recharge a battery and/or power 12 volt electrical appliances
or lights. A starter/generator require a minimum 7/16hp engine running at
a governed 3,600 RPM for it to produce a regulated 15 amps @ 13.5 volts.
(15 amps x 13.5 volts = 202.5 watts x 2 = 405 = .4hp engine.) Read on the
back label of the appliance you plan to use for how many amps it draws, then
you'll know if the generator will be able to handle the load.
But on a pulling tractor, if the engine isn't going to have a charging system,
a voltage regulator and wiring isn't required as long as the battery is fully
charged with a
battery charger before the engine is ran again. Plus, the
battery will need to be in a secure place, and route the wiring in a safe
manner. Go here to learn how to repair a Delco-Remy starter/generator:

The Small Engine Alternator/Stator Charging Systems -
Kohler used six different models of stators on their engines. They are rated
at 1.25 amp, which is used only to charge the battery; 3 amp, which is used
to charge the battery and supply power for lights and/or an electric PTO
clutch; and the 10, 15, 25 and 30 amp output stators, which are used to charge
the battery and power heavier electrical loads. And all electric PTO clutches
draw 3 amps of power, so the 3 amp output stator is required for these.
The 1.25 and 3 amp stators doesn't
require an electronic/solid state voltage rectifier/regulator to regulate
the power to recharge the battery because for normal use, an average lawn
and garden engine don't run long enough for the 1.25 and 3 amp stators to
over-charge the battery, or over-power (burn out) the lights and/or an electric
PTO clutch. Instead, these use a rectifier diode to convert alternating current
(AC) to direct current (DC). The low 1.25 and 3 amp output stators require
a rectifier diode to convert the electrical Alternating
Current (AC) to Direct Current (DC) only to recharge the battery.
Filament lights and electric PTO clutches don't require direct current, so
they can operate without a diode.
Troubleshooting a 3 Amp Battery Charging System with the 70 Watt
Lighting/Electric PTO Clutch Stator -
Certain Kohler engines with the 1.25 or 3 amp stator use a diode and not
a voltage rectifier/regulator. To find out why one of these charging systems
isn't generating any power, remove the flywheel and see if any of the magnets
inside the flywheel are cracked, loose or missing. Next, check to see if
the windings on the stator are burned up or damaged. If they are not burned
up or damaged, then they should be in good condition. But to make sure, use
a multimeter set on the Ohms resistance, connect the black wire on the meter
to engine ground. and connect the red wire on the meter to the BLACK wire
coming from the stator, then connect the YELLOW wire. If the meter shows
continuity for either wire, then the windings are in good condition. But
if there's no continuity, then there's a break (open circuit) in either windings
to ground . The windings either needs to be repaired or the stator needs
to be replaced. If all of this looks good, and either charging system still
will not generate a charge to the battery, then chances are, the diode was
overloaded and got burned up, and needs replacing. The diode is part of the
BLACK wire coming from the stator, and there should be a "lump" in the BLACK
wire. This is where the diode is located. It's probably covered with the
plastic sheath and/or
heat shrinkable tubing. You can replace it with a 3 amp/12
volt diode. Be sure to install the diode with the silver stripe toward the
stator.
But the high-output stators (10, 15, 25, 30 amp or more), rather it's a charging
stator under the flywheel on a small engine or belt-driven automotive-type
alternator, require an electronic/solid state voltage "rectifier/regulator"
to convert the alternating current (AC) to direct current (DC) and to regulate
the amount of charge into the battery and limit the amount of voltage throughout
the entire electrical system while powering electrical accessories at the
same time. The faster the engine runs, the more voltage and amperage the
stator produces.
Although very reliable, weather-proof and virtually maintenance-free, this
system produces an adequate charge at low idle speeds.
This system is the standard of today's charging systems used on virtually
all small engines, motorcycles, snowmobiles, automotive engines, heavy equipment
machinery, etc.
And unlike the belt-driven automotive-type alternator, an alternator/stator
under the flywheel is self-energizing. It will produce electricity when the
flywheel is spun fast enough.
How to Identify the Three Wires Coming from an Engine -
Use a digital or analog multimeter set on the ohms
(d) resistance to test each wire coming from
the engine. With the engine not running, ground one test lead to the engine,
and connect the other lead to each wire one at a time. If one wire shows
resistance, this is the ignition kill wire. If the engine has points, the
crankshaft may need to be rotated by hand until the wire shows resistance.
(This is when the points close.) And if the other two wires show no resistance,
these are the charging stator lead wires. When the test leads are connected
to the two wires with no resistance, they should show 100% resistance. These
two wires connect to the voltage regulator/rectifier. Be sure to mark each
wire with masking tape or something to identify them.
How to Test the Condition of a Small Engine
Alternator Charging Stator - [Top of Page]
First of all, all charging stators produce alternating current (AC) voltage
and there's a diode built into the electronic/solid state voltage
rectifier/regulator. (Rectifier = converts alternating current (AC) to direct
current (DC); Regulator = regulates voltage to recharge the battery and limits
power to electrical accessories, such as lights, electric PTO clutch, etc.)
If the diode is shorted, it'll drain the battery and may burn up the stator
windings. The wire windings on the stator are not grounded, they're isolated
from the engine block. And debris/dirt on the stator or on the magnets in
the flywheel do not weaken the magnetism to the stator whatsoever. Stators
rarely become defective, unless the two wires are connected to each other
while the engine is running, causing a short.
To test the condition of a stator with the engine not running, or
with the stator removed from the engine (check to see of there's any wire
windings on the stator that's damaged or broken from being mishandled), use
an
analog or
digital multimeter set on ohms
(d) resistance. Disconnect the two wires from
the voltage rectifier/regulator, connect one stator wire to one test lead
and connect the other test lead to the metal frame of the stator or engine
block (installed stator). Notice the reading, and then do the same for the
other stator wire. The meter should show no resistance with either wire.
Then connect the two wires on the stator to the test leads on the meter.
If the meter shows full resistance, the stator is likely in good condition.
This testing procedure applies to all makes and models of small engines,
including motorcycles and snowmobiles, foreign or domestic, with the charging
stator located under the flywheel.
To test the voltage output of a stator with the engine running, use
an
analog or
digital multimeter set at more than 36 volts in the AC
setting. With the engine running at full governed speed set at 3,600
RPM, for a (4-5/8" O.D.) 10 amp stator, the reading should be in the
range of 20 volts. For a (5-1/2" O.D.) 15 amp stator, the reading should
be in the range of 28 volts. For a (5-1/2" O.D.) 20 amp stator, the reading
should be in the range of 36 volts. If it's less than 20, 28 or 36 volts
(according to the amperage of the stator), the stator may be defective and
should either be repaired (if possible) or replaced. Or maybe a ceramic magnet
inside the flywheel is cracked, or on a rare occasion, magnet(s) may be missing
(wrong type of flywheel installed on the engine). A magnet with a chip should
work fine, as long as it's not cracked or broken in two. Anyway, when testing
the voltage output of a stator, if the reading is more than 20, 28 or 36
volts, the windings may be shorted (making contact with each other), resulting
in the excessive increase of voltage, which would likely cause the voltage
rectifier/regulator go bad, and possibly also burn up the acid in the battery,
primary windings in the ignition coil and/or overpower electrical accessories.
This test procedure applies to all makes and models of small engines, gas
or diesel, including motorcycles and snowmobiles, foreign or domestic, with
the charging stator located under the flywheel.
Do not touch the
two wire terminals or the energizing coils wire on the stator with your bare
hands while the engine is running! Electrical shock or electrocution could
result!
How to Test an Electronic/Solid State Voltage Rectifier/Regulator -


The easiest and most accurate way to test an electronic/solid
state voltage rectifier/regulator is with an
analog or
digital multimeter set in the DC setting above 12 volts,
and with a known good charging stator installed in an engine while the engine
is running. With the engine off, connect the stator's two wires to the
rectifier/regulator's two outer terminals (being it's AC, it doesn't matter
which wire connects to which terminal). With the engine running at 3,200
RPM (when the engine has a fixed/non-adjustable main jet carburetor) or 3,600
RPM (when the engine has an adjustable main jet carburetor), check the voltage
output at the center terminal on the rectifier/regulator. If the voltmeter
displays or reads 14.5 volts, the rectifier/regulator is good. If less than
14.5 volts or no voltage, the rectifier/regulator is defective. By the way
- the older rectifier/regulator with fins works the same as the newer ones
with no fins. Also, the small size voltage rectifier/regulator is to be mounted
in the opening of the flywheel shroud of a Kohler AQS (Quiet Line) engine
so cool incoming air from the flywheel will keep the regulator unit from
overheating while in operation. If it's mounted elsewhere with no cool air
blowing over it, it could burn up prematurely.
Make sure the slip-on spade crimp connectors on the stator's wires are in
good condition and fit snug on the terminals of the electronic/solid state
voltage rectifier/regulator. If the scrimp connectors fit loose or have a
faulty connection due to rust, they could arc during heavy charging and burn
out the terminal(s) on the voltage rectifier/regulator, and/or heat from
the arcing could travel inside the voltage rectifier/regulator and burn it
out.
Go here for more information:
The rectifier-regulator must match
the amperage output of the stator it's connected to. If a 15 amp
rectifier/regulator is used with a 25 or 30 amp stator, the rectifier/regulator
will burn up. A 32 amp electronic/solid state voltage rectifier/regulator
that's designed for Harley-Davidson motorcycles will work with the Kohler
30 amp stator. The starter/generators and voltage regulators used on all
garden tractors are rated at 15 amps. And an analog voltage regulator can't
be used with an AC alternator stator, nor the electronic voltage
rectifier/regulator can't be used with a DC generator.
To connect an alternator stator... the two leads from the stator connects
to the two outer terminals on the rectifier-regulator. The center terminal
on the rectifier-regulator then connects to the battery's + post or the ignition
switch that connects to the battery's + post. It's that simple. And the
electronic/solid state voltage rectifier/regulator has diodes built-in. So
there's no need to add diodes in the circuit.
How to Replace the Charging Stator on a Kohler engine -
-
Remove the flywheel.
-
Remove the four Phillips head screws that secures the stator to the bearing
plate. If the screws refuse to loosen, strike the end of the screwdriver
with a medium size hammer at the same time while turning the screw.
-
Remove the clamp that secures the stator wires to the bearing plate. This
clamp is to prevent the wires from making contact with the flywheel.
-
Disconnect plastic connector housing/terminals from the electronic/solid
state voltage rectifier/regulator.
-
With a small, flat screwdriver, depress the locking tab/tang (see drawing
above È) on each terminal that secures
the terminals in the plastic connector housing. Pull the terminals from the
plastic connector housing. Inspect the terminals for damage. Replace them
with the same type terminals and reuse the plastic connector housing, or
replace them with ordinary crimp-type slip-on terminals and discard the plastic
connector housing. IMPORTANT - The stator wires ALWAYS connect to the
two outer terminals on the electronic/solid state voltage rectifier/regulator
(it doesn't matter which wire connects to which terminal), and the battery
(+) positive wire connects to the center terminal.
-
The stator can now be removed from the engine.
-
Installation is in reverse order of removal.
Converting the old starter/generator charging system to the newer,
alternator-equipped charging system -
First off, all of the K241-K361 Kohler flywheels will interchange. The crankshaft
tapers are the same. They're the same weight, too. The alternator stator-type
charging system will also work on a narrow frame Cub Cadet, but the tractor
frame rails must be widened to accept the larger diameter flywheel, bearing
plate and shroud. The larger bearing plate will accept the stator/charging
ring. And you'll need an electronic/solid state voltage rectifier/regulator
that's capable of handling the amount of amps that the stator will produce.
Stators installed on most Kohler engines have a 15, 20, 25 or 30 amp output.
Most common are the 15 or 20 amp stators. To identify the amount of amps
a stator can produce...
-

The ordinary 15 amp stator has 18 poles, but only 16 are wound
with wire and the other two are empty. This stator has 2 wire leads.
-
The 15 amp stator for Breakerless Ignition also has 18 poles. All 18 are
wound with wire, 16 poles are for charging the battery and powering electrical
accessories, and the other two poles are to energize the Module Sensor. This
stator has 3 wire leads, 2 for charging, and the 3rd for the module.
-
The 25 amp stator also has 18 poles, all of them are used and heavily wound
with wire. This stator has 2 wire leads. This stator is rare.
-
The 30 amp stator has 12 poles, which are very heavily wound with wire and
have 4 wire leads. This stator is also rare.
If an electronic/solid state voltage rectifier/regulator that's made for
a smaller [amperage] output is used with a higher amp output stator, it'll
burn up in no time. Remember, the higher the amperage of a charging system,
the more horsepower it'll draw from the engine (when under a heavy charging
load). For wiring diagrams of various Cub Cadets, see this web site:

How to Reinstall or Replace the Charging Magnets
in a Kohler or Tecumseh Flywheel - [Top of Page]
Kohler used to install aluminum
expansion roll pins to secure the ceramic magnets inside the flywheel. Which
worked very well. Then they dropped this design and glued them in instead.
Now people are having problems with the magnets coming loose. And sometimes
the loose magnets will damage the stator. Anyway, when a magnet becomes loose
inside the flywheel, if it is not broken, it can be reinstalled with
Krazy Glue,
Super Glue,
Gorilla Glue, or any industrial strength adhesive. Broken
magnets cannot be reused. A broken magnet must be replaced with an identical
magnet in good condition. A broken magnet actually becomes two magnets
with a north and south pole on each broken piece, and will not work at all
in a small engine alternator/stator charging system. Even if the two pieces
are glued together, the magnetic poles may or may not attract, and the molecules
cannot bond together to form one single magnet.
When the flywheel is removed and all the magnets are stuck to the stator,
remove the magnets and place them someplace where so they're be in the order
that they were in the flywheel or on the stator (don't mix them up). Thoroughly
clean the outside curve of each magnet and the inside of the flywheel with
electrical contact cleaner,
brake parts cleaner,
cleaning solvent or
paint thinner (these leave no oily residue), and then reinstall
the magnets in the order they were removed with
Krazy Glue,
Super Glue,
Gorilla Glue, or any industrial strength adhesive. Make
sure the magnets are equally spaced apart, too.
To remove good, reusable ceramic magnets from a flywheel (for whatever reason),
first of all, use a
Sharpie metallic silver permanent marker or
paint marker to place a number on each magnet in their
proper position in the flywheel (1-2-3-4-5-6) so they can be reinstalled
in the correct order. For magnets that's held in place with aluminum compression
pins, simply use an 1/8" roll pin punch and a medium size hammer to drive
out one pin toward the center of the flywheel, then all the magnets will
be loose and can be removed from the flywheel by hand. For magnets that's
held in place with glue, use a
propane torch or an
oxy-acetylene torch with a small flame to heat the cast
iron part of the flywheel on the outer (glued) part of each magnet to soften
the glue, and then CAREFULLY and GENTLY remove the magnets with a
thin, sharpened steel
putty knife or scraper and small hammer. Do not apply heat
directly to the magnet itself, it could break! Due to the heating process,
and to prevent from being burned, use a shop towel to handle each hot magnet.
TO AVOID BREAKAGE, DO NOT COOL CERAMIC MAGNETS WITH WATER! Allow them to
air-cool.
Internal flywheel charging magnets are of a very
odd type. Charging magnets in the Kohler and Tecumseh flywheels do not
have just North and South magnetic pole ends, such as the typical U-shape
or horseshoe magnets. Unlike ordinary magnets, these are NOT just North-South
and vice-versa on the ends, no exceptions. There are a total of six magnets
in most Kohler flywheels. Three are South-North-South on the inside curve
and North-South-North on the outside curve, and the other three magnets are
North-South-North on the inside curve and South-North-South on the outside
curve. Each charging magnet is like three magnets integrated into one. This
is how the charging system generate so much voltage and amperage.
Referring to the photo with the two charging magnets above, the magnet on
the left is polarized South-North-South on the inside curve and North-South-North
on the outside curve. And the magnet on the right is polarized North-South-North
on the inside curve and South-North-South on the outside curve.



To identify which pole is
which, from the inside curve of each magnet (not the outside curve), use
a high quality
portable handheld magnetic compass or use another [strong]
magnet with the magnetic poles identified and marked to identify the magnetic
poles of each flywheel magnet. Always identify the magnetic poles from the
inside curve of each magnet, and not the outside curve. By the way - As business
is booming, when the magnetic North and South poles on a U-shape or horseshoe
magnet isn't marked or identified, to correctly find which pole is which,
fasten a thin string or sewing thread to the middle of the magnet, and allow
it to dangle in midair. It may take a few minutes for the string or thread
to unwind so the magnet will stop spinning and come to a full rest. Make
sure no other magnets are nearby. The ends of the magnet to be tested will
attract to the Earth's natural North and South magnetic poles. When the poles
have been identified, mark which pole is which with a
Sharpie metallic silver permanent marker or
paint marker for future reference. Dangling Kohler flywheel
charging magnets by a string to identify the poles will not work. A magnet
with identified North and South poles must be used to identify the poles
on a Kohler flywheel charging magnet. And use caution when handling ceramic
(flywheel) magnets! They are very brittle and can break easily if mishandled.
Do not allow them to quickly snap together or quickly attract to a large
steel or cast iron object. Return to
previous paragraph or website.
If anyone tells you that there is no certain order charging magnets are
reinstalled or replaced in a flywheel, then they are wrong! If they are installed
misaligned or not in the correct order, the charging system will NOT work.
They MUST be reinstalled in the correct order with the poles (end of each
magnet) opposite of each other for the charging system to work correctly.
Before installing magnet(s) in the flywheel, clean both the flywheel and
outside curve of the magnet(s) thoroughly with
electrical contact cleaner,
brake parts cleaner,
cleaning solvent or
paint thinner (these leave no oily residue). Then use soap
and clean water afterwards to remove any dirt or debris. When installing
the magnet(s), it's important that the north and south pole ends of each
magnet is in correct alignment, with the pole ends opposite of each other.
When the poles physically attract, they're in the correct alignment. Use
Krazy Glue,
Super Glue,
Gorilla Glue, or any industrial strength adhesive. Make
sure the magnets are spaced equally apart upon installation, too. Go here

Using a 12 Volt Automotive Generator or
Alternator with a Small Engine to Recharge the Battery and/or Power Electrical
Accessories - [Top of Page]

If an [older] small engine have an obsolete charging system,
or if the magnet(s) in the flywheel are broken or missing, and there's no
magnets available, or if there's no stator or voltage regulator available,
or if repairing the original charging system is cost prohibitive, well, if
there's enough space in the engine compartment, an early automotive
12 volt Delco-Remy DC generator can be used instead. This
"generator" is different than the "generator/starter." The "generator" can
only supply electrical power to recharge the battery and power electrical
accessories, and don't have enough energy to crank over an average small
engine to start it. Anyway, the "generator" produce up to 30 amps of power,
so recharging the battery and/or powering electrical accessories is somewhat
limited. The
12 volt Delco-Remy DC generator came on all 1955-1961 GM
cars and trucks. Other makes and models of automobiles of this time period
used a similar DC generator unit. In 1954 and earlier, all cars and trucks
used a 25-45 amp 6 volt DC generator to recharge the 6 volt battery and power
6 volt light bulbs and heater blower motor. Again, other makes and models
of automobiles of this time period used a similar DC generator unit. A
12 volt Delco-Remy DC 30 amp generator requires a minimum
1 horsepower engine to produce the most power when under full load. (30 [amps]
x 12 [volts] = 360 [watts] x 2 = 720, which converts to .72 horsepower.)
And a
12 volt DC 45 amp generator requires a minimum 1-1/2 horsepower
engine to produce the most power when under full load. (45 [amps] x 12 [volts]
= 540 [watts] x 2 = 1080, which converts to 1.08 horsepower.) If a too small
of engine is used with any particular size generator, the engine will die
when the electrical energy is under full load. The engine speed will need
to be set at 2,500 RPMs or up to 3,600 RPM (maximum governed speed) depending
on the electrical load. Install a 12 volt voltmeter to monitor that the generator
is in fact producing 12 (actually 13.5) volts at all times.

However, if more amps are required to power some "heavy duty"
12 volt electrical accessories that draws a lot of amps, a high amp
automotive alternator can be used with a small engine.
It doesn't matter about the rotation direction of the armature in the alternator,
because they all produce AC voltage and the diodes inside them convert the
AC to 13.5 volts DC output to recharge a 12 volt battery and power 12 volt
electrical accessories. Modern ordinary
automotive alternators produce anywhere from 65-100 amps
of power at 1,500+ engine RPM (most belt-driven alternators and generators
turn about 3-1/2 times faster [3.5:1 ratio] than the engine). But the high-output
automotive alternators produce 200-350 amps of power at 1,500+ engine RPM.
Alternators from the late 1970's-1990's automobiles incorporate the voltage
regulator/rectifier in the alternator housing. Modern designs do away with
the voltage regulator/rectifier altogether; voltage regulation is now a function
of the computerized electronic control unit (ECU). By the way - being all
automotive alternators have a built-in voltage regulator/rectifier, which
"rectify" or convert alternating current (AC) to direct
current (DC), there is no electronic/solid state "voltage regulator/rectifier"
associated with these units. It's referred to as just the "voltage regulator."
An
automotive alternator that produces a maximum of 60 amps
will require a minimum 1.44 of engine horsepower. (60 [amps] x 12 [volts]
= 720 [watts] x 2 = 1440, which converts to 1.44 horsepower.) An alternator
that produces a maximum of 350 amps will require a minimum 8.4 of engine
horsepower. (350 [amps] x 12 [volts] = 4200 [watts] x 2 = 8400, which converts
to 8.4 horsepower.) If a too small of engine is used with any particular
size generator, the engine will die when the electrical energy is under full
load. So when using an alternator that produces more amps, be sure to use
a big enough engine to handle the amperage, or the engine will bog down or
if the belt tension is not tight enough, the V-belt will slip when a heavy
electrical load is placed on the alternator. The engine speed will need to
be set at 2,500 RPMs or up to 3,600 RPM (maximum governed speed) depending
on the electrical load. Install a 12 volt voltmeter to monitor that the
alternator is in fact producing 12 (actually 13.5) volts at all times.

A
belt-driven automotive-type alternator or various direct-drive 120/240 AC
volt portable [household] generators require a small electrical charge to
energize the field windings so it will produce electricity as soon as the
engine starts. Otherwise, the alternator or generator will not produce
electricity. In an automobile, the current for the field windings is supplied
by the battery through the ignition switch while the engine is being started,
and once the engine is started, the armature windings (on the stator) generate
enough current and voltage to power the field windings, so the alternator
becomes self-exciting and no external power source is needed to power the
field winding. But with a small engine and no battery and starter motor (recoil
starter only) the field windings needs to be energized with an external power
source to make it work. The field windings in the alternator/generator can
be energized by the engine's ignition system (magneto or battery-powered)
or small charging stator under the flywheel with use of a two wire rectifier
diode. The wire on the end of the diode with the colored stripe (cathode
()) will need to be connected to the field windings, and the
other wire on the diode (anode (+)) connects to the wire between the points
and condenser/capacitor and battery-ignition coil, or the [kill] wire between
the electronic/solid state ignition
module and magneto coil. Electricity can only travel in one direction
in a diode. Therefore, use of a diode in this application will prevent any
current from the alternator or generator from disrupting the ignition system
or burning out the electronic/solid state module.
And to prevent from burning up the windings, install an
inline fuse holder or circuit breaker in case the alternator
or generator gets severely overloaded. To determine the size of fuse or circuit
breaker, figure how many amps all the connected electrical accessories draw,
then use a fuse or an automatic circuit breaker with an amp rating slightly
higher to prevent the fuse from burning out or the circuit breaker from
overloading and popping. If the alternator or generator is severely overloaded,
the fuse will need to be replaced and the circuit breaker will automatically
reset itself.
FYI - Amps is converted into watts simply by multiplying the known amps
by the full voltage, which will display the full watts. And watts is converted
[back] into amps by dividing the known watts by the full voltage, which will
display the full amps. To find the amount of amps or watts any particular
appliance require, look on the manufacturer's label or sticker. It should
display it there. If the amps draw is unknown, then an
amp tester will need to be used. If connecting multiple
appliances together to one generator, add up the amps or watts of each appliance,
and that should tell you the total amps or watts will be required to power
everything.
The old style alternators with the V-belt pulley will rob the engine of more
power than the new style alternators with the serpentine belt pulley. Anyway,
to have a small engine drive an
automotive alternator, install an automotive pulley (serpentine
or V-belt) on the flywheel or PTO end of the engine, and make sure it's centered
so it'll turn true and not wobble. Most automotive alternators spin about
3-1/2 times faster than the engine to produce full charge. So at 1,500 engine
RPM, and with a 3.5:1 increase in ratio, the alternator spins at 5,250 RPM.
This means the engine drive pulley will need to be 3-1/2 times bigger than
the pulley on the alternator so the alternator will produce full charge.
Align and mount the engine and alternator side by side so the alternator
can be spun 3-1/2 times faster than the engine RPM. Do not mount them so
they'll be directly in-line with each other. Doing this would allow the
alternator to be driven at a the same speed as the engine (1:1 ratio), and
it won't be able to spin fast enough to produce full charge. If space is
an issue, a [small] 1970s-1990s model import car or truck alternator can
be used. The 1970s-1990s alternators have just one terminal, which connects
directly to the battery's positive (+) post. Fabricate a bracket to install
the alternator and a slotted adjusting bracket to adjust/tighten the belt.
And as long the engine is running fast enough for the alternator to produce
full charge (approximately 2,000 RPM), it wouldn't matter if the engine is
running any faster, because the alternator will only produce a certain amount
of amperage and voltage. Finally, if the engine bogs down slightly while
the alternator is under a heavy electrical load, this means the alternator
is working perfectly. And to prevent from burning up the windings, install
an
inline fuse holder or circuit breaker in case the alternator
or generator gets severely overloaded. To determine the size of fuse or circuit
breaker, figure how many amps all the connected electrical accessories draw,
then use a fuse or an automatic circuit breaker with an amp rating slightly
higher to prevent the fuse from burning out or the circuit breaker from
overloading and popping. If the alternator or generator is severely overloaded,
the fuse will need to be replaced and the circuit breaker will automatically
reset itself. Having a fuse or circuit breaker (and
ammeter/amp gauge if the engine has a charging system)
installed is very important to prevent failure of electrical components.
By the time you smell something burning or see smoke, it may be too late.

will need to be used. Otherwise, the generator can be belt-driven with a
1:1 ratio. And being the generator produces AC current, with most of them,
it doesn't matter which rotation it turns (clockwise or counter-clockwise).
But if it is directional, make sure it rotates in the right direction. And
to match the generator to the engine or vice-versa, the generator output
kilowatts will need to be half the horsepower of the engine. For example:
a 5,000 watt (5 KW) generator will require a minimum 10hp engine, a 6,000
(6 KW) watt generator will require a minimum 12hp engine, etc. If a too small
of an engine is used with a too big of a generator, the engine will probably
lug down or possibly die when under a severe electrical load. The same will
happen if the engine is in need of an overhaul to boost the horsepower. A
120 volt plug-in voltmeter is required to set the engine
RPM so the generator will produce exactly 120 volts of power. And to prevent
from burning up the windings, install an
inline fuse holder or circuit breaker in case the alternator
or generator gets severely overloaded. To determine the size of fuse or circuit
breaker, figure how many amps all the connected electrical accessories draw,
then use a fuse or an automatic circuit breaker with an amp rating slightly
higher to prevent the fuse from burning out or the circuit breaker from
overloading and popping. If the alternator or generator is severely overloaded,
the fuse will need to be replaced and the circuit breaker will automatically
reset itself. Having a fuse or circuit breaker (and
ammeter/amp gauge if the engine has a charging system)
installed is very important to prevent failure of electrical components.
By the time you smell something burning or see smoke, it may be too late.
Whenever a defective automotive battery that's under warranty is returned
for a refund or exchange, most businesses that sold the battery will test
it by putting a charge in it, then load test it to verify that if it is in
fact defective. And sometimes the place will say that the battery tested
good and is in good condition, when you are sure that it's defective, but
they won't honor their warranty, and the argument begins. So what can be
done is, drain the acid out of the battery (properly dispose the acid) and
fill it with plain water. Then when the place test it, they'll say, "yep,
it's defective!" and there's no argument.

FYI - The self-propelled garden tractor pulling sled that I built is such
an excellent design, I realized later that I made something very special
when other people copied after it. - Brian Miller

To place an order, please call the number listed
below Ê or send an email with your name,
complete and correct postal address and phone number and so I can figure
the total with shipping cost and USPS Tracking. For payment options for parts
ordered or services performed, or to make a donation to my websites, I accept
cash (in person), USPS Postal Money Orders, cashier's checks, business checks,
MasterCard, VISA, Discover, American Express (please add 2.5% to the total
for the credit/debit card processor's surcharge),
Western
Union Money Transfer or MoneyGram
Money Transfers. (If a part for a specific purpose is special ordered,
your debit/credit card may be charged for the full amount or as a deposit
right after your order is placed; please do not send your debit/credit card
information in email!) Or you can pay A-1 Miller's through PayPal. (My PayPal
account name is my email address. And be sure to mention in PayPal a description
of what the payment is for.) If sending a money order, please include a note
in the envelope with your name, complete and correct postal address, phone
number and a description of what the payment is for. My mailing address and
phone number are listed below Ê . I'll
make a note of your order, and I may have to order some of the parts, which
should take a few days to come in, but I will send the parts to you as soon
as I have everything in stock after I receive your payment.
IMPORTANT - When sending your part(s) to A-1 Miller's
for rebuilding or repair, package everything securely so the item(s) won't
get damaged in shipping and please include a note in the box with your name,
mailing address, phone number (in case I have any questions) and a description
of what you want done. When shipping heavy parts, it's best to put a slightly
smaller box inside a larger box, to double the strength and integrity of
the package. Because the clumsy "gorillas" or incompetent and uncaring workers
that work for certain delivery services mishandle the heavy packages and
don't care. And when the work is completed, I'll either call or email you
an invoice with the total including shipping & handling.
Payment Options and We Ship to Canada and
Worldwide 
Item(s) in a package or cushioned envelope weighing less than 1 lb. is sent
by US Postal Service Airmail Letter Post for a 4-7 days delivery. Packaged
item(s) weighing over 1 lb. and up to 66 lb. is sent by US Postal Service
Airmail Parcel Post for a 4-10 days delivery. I cannot use the US Postal
Services' Flat Rate Priority Mail envelopes and boxes to ship outside U.S.
territories. Item(s) weighing over 67 lbs. or more is sent by FedEx Ground
or equivalent services. We try to keep our shipping cost to customers within
reason. Therefore, we don't ship our products in a fancy-looking package
with our company name and/or logo on it because most customers will just
toss it in the trash after they remove the contents. And being there is no
USPS tracking number outside the US, all I can do is make sure I write your
address correctly on the customs form and on your package.
My websites are not set up to process orders and accept payments. Therefore,
for payment options, I accept cash (in person), USPS Postal Money Orders,
