TROUBLESHOOTING CHARTS

NO SPARK

Disconnect the single black (black/white) wire from the
CDI Module to the ignition kill circuit. Does it have a
spark?
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?
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.
Follow the engine timing procedure for checking
running timing at recommended RPM. Is the timing
within limits?
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?
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?
Check the resistance of the coils under the flywheel.
Compare these to values on wiring diagram. Are they
within limits?
13.14
Table 13-7: No Spark Condition
YES
Table 13-8: Incorrect Timing (Advanced/Retard)
YES
YES
Check the ignition switch, wire harness, throttle safety
switches and kill switch for proper adjustment or short
NO
to ground. Repair or replace as necessary.
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)
NO
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.
Adjust the ignition timing by rotating the stator plate to
correct the timing. After adjusting the recommended
NO RPM timing, continue with operating RPM timing if
poor performance exists. (Continue on with left
column.)
Check the ignition switch, throttle safety switches, kill
NO switch and harness for damage which can cause
intermittent shorting problems. Correct the problem.
Replace the module with the correct part and readjust
NO
the ignition timing.
Check the wiring connecting the coils and/or replace
NO
the coils as necessary.
