TROUBLESHOOTING TABLES
NO SPARK
No Spark Condition
Disconnect the single black (black/white) wire from the CDI Module to the
ignition kill circuit. Does it have a spark?
NO
J
Check the ignition switch, wire harness, throttle safety switches and kill
switch for proper adjustment or short to ground. Repair or replace as
necessary.
YES

Disconnect the stator to CDI module wires. Test the resistance values of the
stator coils as per the wiring diagrams. Are the resistance values within
specs?
NO
J
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.
YES

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.
Incorrect Timing (Advanced/Retard)
Follow the engine timing procedure for checking running timing at
recommended RPM. Is the timing within limits?
NO
J
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.)
YES

Remove the ignition kill circuit by disconnecting the single black wire between
the CDI module and the machine harness. Is the timing now correct?
NO
J
Check the ignition switch, throttle safety switches, kill switch and harness for
damage which can cause intermittent shorting problems. Correct the
problem.
YES

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
J
Replace the module with the correct part and readjust the ignition timing.
YES

Check the resistance of the coils under the flywheel. Compare these to
values on wiring diagram. Are they within limits?
NO
J
Check the wiring connecting the coils and/or replace the coils as necessary.
