② Check for continuity between any stator lead and
stator core.
If there is continuity, it means that the coil is
grounded.
Replace the stator assembly.
(3) Rectifier Assembly
① Positive Heatsink
Check for continuity between the positive (+) heat
sink and stator coil lead connection terminal with a
circuit tester.
If there is continuity in both directions, the diode is
short-circuited.
Replace the rectifier assembly.
② Negative Heatsink
Check for continuity between the negative (-) heat
sink and stator coil lead connection terminal with a
circuit tester.
If there is continuity in both directions, the diode is
short-circuited.
Replace the rectifier assembly.
③ Diode Trio
Using a circuit tester, check the three small diodes
for continuity in both directions.
If there is either continuity or an open circuit in
both directions, the diode is defective.
Replace the rectifier assembly.
