WARNING
When checking the peak voltage do not
touch any of the connections of the digital
tester lead wires.
NOTE:
• If there is no spark or the spark is weak,
continue with the ignition system test.
• If a good spark is obtained, the problem is
not with the ignition system, but possibly
with the spark plug(s) or another compo-
nent.
1. Measure:
• CDI unit output peak voltage
