Checking the ignition coil
1. Remove the spark plug caps from the
high-tension cords by turning the caps
counterclockwise.
2. Measure the ignition coil resistance.
Replace if out of specification.
Checking the CDI unit
1. Measure the CDI unit output peak volt-
age. If below specification, measure the
charge coil output peak voltage and the
pulser coil output peak voltage. Replace
the CDI unit if the output peak voltage of
both coils is above specification.
WARNING
When checking the peak voltage do not
touch any of the connections of the digital
tester leads.
NOTE:
• Use the peak voltage adaptor with the digi-
tal circuit tester.
• When measuring the peak voltage, set the
selector on the digital circuit tester to the
DC voltage mode
.
Checking the charge coil
1. Measure the charge coil output peak volt-
age. Replace the stator coil if below
specification.
