IGNITION SYSTEM
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.
1. Measure:
CDI unit output peak voltage
Above specification → Normal
Below specification → Measure the
rectifier output peak voltage. Replace
the CDI unit.
CDI unit output peak voltage:
Black/White (B/W) – Black (B):
Black/Orange (B/O) – Black (B):
125 V @ 400 r/min (cranking)
130 V @ 1,500 r/min
130 V @ 3,500 r/min
NOTE:
B/W – B for cylinders #2 and #3.
B/O – B for cylinders #1 and #4.
