IGNITION SYSTEM PEAK VOLTAGE

WARNING
When checking the CDI unit 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.

CDI unit output peak voltage
Above specification → Normal
Below specification → Measure the
