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 stator coils as per the wiring diagrams. Are the resistance val-
ues within specs?
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 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.
