KT17 & KT19 Electronic Ignition Conversion Kit Installation Instructions

Electronic Ignition Conversion Kit below specifically made for KT17 first design and KT19 first design engines includes: New PerTronix Ignitor hall effect module/sensor fastened on adjustable/slotted aluminum mounting plate, two 10-24 UNC screws w/flat washers and lock washers, two aluminum spacers, target screw w/magnet and rubber cushioning washer, two new Autolite 26 or Champion 25 (RV17YC) spark plugs, and points pushrod hole block-off plate (use with silicone sealant). Use this ignition system with the OEM off-ignition-start key switch and dual wire ignition coil.

INSTALLATION INSTRUCTIONS for KT17 first design and KT19 first design engines. This option can also be used on the KT17 Series II and KT19 Series II engines, and perhaps Magnum engines with the KT-series flywheel installed. Video of this ignition system installed on a running engine coming soon.

  1. Use a Sharpie metallic silver permanent marker to locate and install the trigger screw w/magnet and rubber cushioning washer on the flat area on the flywheel above the T mark as shown in the picture to the right. This will place the ignition timing in alignment with the center of the PerTronix Ignitor module/sensor when the S mark on the flywheel is in exact alignment with the roll pin on the cylinder (which is positioned at 23º BTDC). The screw head is magnetized to trigger the spark. There is no need to remove the flywheel to drill and tap the threads. The screw hole must be professionally drilled and tapped to accept the supplied 6-32 UNC trigger screw with a [preferably] TAPER hand tap. Click here to learn how to professionally cut new threads. To prevent from breaking off drill bit or tap, secure the flywheel so it does not rotate one way or the other while drilling hole and/or cutting threads! NOTE: The rubber washer prevents the brittle rare earth/neodymium magnet from breaking when the screw is tightened. IMPORTANT: Secure the screw in the flywheel with high strength liquid threadlocker (Red Loctite, Permatex or equivalent) and tighten it just until the rubber washer begin to bulge. The PerTronix Ignitor hall effect module/sensor is activated by the South pole of the magnet, so do not remove the magnet from the screw. FYI - Store a container of liquid threadlocker or Super Glue upright and not laying flat. The capped tip will not dry out and clog when stored upright.
  2. Being there are no two bosses on the #1 cylinder (right side of engine when facing the flywheel) of the KT17 first design and KT19 first design engines, use the side of the valve spring compartment casting on the #1 cylinder facing the flywheel to mount the two supplied posts/supports for the supplied mounting plate with the ignition module/sensor. See the [mock up]picture to the right.->
  3. On the #1 cylinder, remove the crankcase breather assembly and plug the crankcase breather vent hole leading into the crankcase. This will prevent drill cuttings from entering into the crankcase, which could cause severe engine wear overtime.
  4. On the flywheel side of the valve spring compartment, locate in the general area where to drill and tap two 10-24 UNC screw holes with a [preferably] TAPER hand tap for fastening of the two supports with the mounting plate and ignition module/sensor. There may be no need to remove the flywheel to do this. Click here to learn how to professionally cut new threads. See the [mock up] picture to the right.->
  5. Thoroughly clear out the metal cuttings from inside the valve spring compartment with 150± PSI compressed air. Failure to do this could cause excessive wear to the internal engine parts! Be sure to use eye protection! Then be sure to remove the plug from the crankcase vent hole.
  6. After fastening the two posts/supports with the mounting plate and ignition module/sensor to the side of the valve spring compartment, set the clearance between the module/sensor and trigger screw w/magnet and rubber cushioning washer at .010"-.050" with a paper, plastic or brass feeler gauge, and securely tighten the two supplied 3/16" screws with lock washers to the valve spring compartment. IMPORTANT: Slowly rotate the flywheel back and forth by hand to check that the screw doesn't make contact with module/sensor. If it makes contact, the module could get damaged! On rare occasions, being the casting of the valve spring compartment may be a different width, the mounting plate with the module/sensor may make contact with the side of the ring gear on the flywheel. If this happens, a couple of thin washers (shims) will be need to be installed under the two posts/supports to allow for sufficient clearance.
  7. Simple two wire connections: Connect the RED wire on the module to the positive [+] terminal on the ignition coil (which connects to the ignition switch and positive (+) battery post), and connect the BLACK wire to the negative (–) terminal on the coil. There are no other wire(s) that connect to the negative (–) terminal on the coil. The module/sensor is grounded through the engine to the negative (–) battery post. IMPORTANT: The module/sensor will burn up if the ignition switch is left on for more than a few minutes with the engine not running. To prevent this from possibly happening and/or for security reasons, use an OFF-ON key switch and/or a master disconnect switch with a removable key instead of just a toggle/flip switch to power the ignition system.
  8. Remove the points, pushrod (and condenser) and install the block-off plate to cover the points pushrod hole. Apply RTV silicone sealant to prevent oil leak and use the OEM ignition points mounting screws to secure the block-off plate in place.
