ENGINE ELECTRICAL ±
STATOR CHECK
1. Check the continuity between the coil leads, and if there
is continuity, replace the stator.
2. Check the continuity between the coil and core, and if
there is continuity, replace the stator.
RECTIFIER CHECK
1. Inspect the (+) heat sink by checking the continuity between
the (+) heat sink and stator coil lead wire connection
terminal using a tester probe.
If there is a continuity at both, the diode is short circuited,
so replace the rectifier.
2. Inspect the (±) heat sink by checking the continuity between
the (±) heat sink and stator coil lead wire connection
terminal using a tester probe.
If there is a continuity at both, the diode is short circuited,
so replace the rectifier.
3. Check the diode trio by connecting an ohmmeter to both
ends of each diode and check the continuity of the three
diodes.
If there is a continuity at both ends, or if there is no
continuity, the diode is damaged so replace the rectifier.
