ELECTRICAL 13.17 Condition: No Spark Disconnect the single black (black/white) wire from the CDI Module to the ignition kill circuit. Does it have a spark? Yes! No# Check the ignition switch, wire harness, throttle safety switches and kill switch for proper adjustment or short to ground. Repair or replace as necessary. Disconnect the stator to CDI module wires. Test the resistance values of the Yes! No# All except 3 cylinders: If the parts of the ignition system under the flywheel check OK, the only remaining component is the coil/CDI module assembly. Replace the module with another with the same number. (See ignition data) All 3 cylinders: Disconnect and check the secondary ignition coil resistances. Refer to the resistance values listed in wiring diagrams. If the coil resistance values are within specs, replace the CDI module. Isolate which component’s resistance is not within specs. Remove the flywheel and stator. Recheck the resistances; look for pinched or bare harness wires; or replace the coil. Condition: Incorrect Timing Advance/Retard Follow the engine timing procedure for checking running timing at recommended RPM. Is the timing within limits? No! Yes # Adjust the ignition timing by rotating the stator plate to correct the timing. After adjusting the recommended RPM timing, continue with operating RPM timing if poor performance exists. (Continue on with left column.) Remove the ignition kill circuit by disconnecting the single black wire between the CDI module and the machine harness. Is the timing now correct? Yes! No# Check the ignition switch, throttle safety switches, kill switch and harness for damage which can cause intermittent shorting problems. Correct the problem. Verify the correct CDI module by comparing the CU code on the box to the information listed in the ignition data charts at the beginning of this section. Is it the right module? No! Yes# Replace the module with the correct part and readjust the ignition timing. Check the resistance of the coils under the flywheel. Compare these to values on wiring diagram. Are they within limits? No! Yes# Check the wiring connecting the coils and/or replace the coils as necessary. |
