WARNING
When checking the electrical components,
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
Below specification
→
Measure the
rectifier/regulator output peak volt-
age.
Replace the CDI unit.
NOTE:
B/O – B for cylinder #1.
B/W – B for cylinder #2.
B/Y – B for cylinder #3.
CDI unit output peak voltage:
Black/orange (B/O) – Black (B)
