Harley-Davidson Electronic Ignition Module Installation instructions


Filed Under (Harley Davidson) by admin on 23-04-2012

Step 1: Switch main dashboard switch to “off” position (Ignition& light switch) Step 2: Disconnect negative (ground) cable from the Battery Step 3: Remove the Condenser and Breaker points from the circuit breaker timing base. Step 4: Disconnect advance/ retard cable from timing base Step 5: Remove timing base from timer shaft and housing (see your manual for instructions) Step 6: Remove circuit breaker wire stud or circuit breaker to coil wire assembly from timing base Step 7: Remove circuit breaker wire from Ignition coil, and mark terminal on coil with piece of tape. Step 8: Install the Electronic Ignition Module on the timing base. Mount this short black wire to one on the timer base screws by keeping some slack in this wire so the timing base can turn free. Solder the flag terminal to this short black wire and mount it under the timer to motor bolt. This way of mounting provides a much better grounding. Do NOT use the screws (number 1 or 2 screws from picture below) from the timing base!!!! Step 9: Now three wires pass this hole via the rubber grommet. Figure 1 Figure 2 Step 10: Reinstall the timer base on the timer shaft housing, and keep some slack in the wires before protruding the hole in the timer shaft housing, and secure with ground spring and cover retainer. Reconnect the advance/retard cable to the timer base. Step 11: Route the two long wires to the ignition coil. Check in the HD service manual for a proper route to the ignition coil. (Keep away from hot surfaces like exhaust systems). Cut the wires to the exact length necessary for mounting. Step 12: Determine the exact length of the wire loom. Keep in mind that one end of the loom enters the timer shaft housing by 1cm. Cut the loom to the proper length. Step 13: Insert both wires in the loom. Strip both wire ends and solder the two flag terminals on the wires. Step 14: Connect the red wire to the ignition coil, on the terminal where the 6 or 12 volt is supplied to. This terminal has at minimum one wire connected which runs to the main switch. Step 15: Connect the black wire to the ignition coil on the terminal which is empty, and has piece of tape on it. (Old place where the circuit breaker wire was connected to) Step 16: Install the trigger rotor on the timer shaft cam, and tighten the hex screw by using the hex key tool. Do not over tighten the screw! Step 17: Check for clearance between trigger rotor and Electronic Ignition Module. Appropriate clearance is between 0,5mm and 1,5mm . Minor adjustments can be made by unlocking the two screws and slightly shift/move the Electronic Ignition Module. Check if the rotor moves free. Timing instructions: Remove the spark plugs from the engine, but keep them connected to the spark coil cables and engine ground. This enables normal operation of the spark, and prevents unwanted engine firing on compression stroke. See service manual or handbook for timing instructions of your model Step 18: Reconnect the negative (ground) cable to the battery. Step 19: Switch main power to “on” position. The red light in the Electronic Ignition Module might already light up. If not, turn the kick starter slowly. The red light is on while charging (closed points)the Ignition coil, facing solid metal of the trigger rotor. The light goes off (open points) when the end of the solid surface of the trigger rotor passes the centre of the Electronic Ignition Module. At that point a spark is generated by the coil
