D

Test the stator for open or ground circuits by using
the ohmmeter. The reading should be sufficiently
high, or the stator must be replaced (2).

D102E753

3. Inspect the rectifier.

D

Positive rectifier test:
Inspect the open circuit for stator coil lead termi-
nals using the ohmmeter (1).
Replace the rectifier if necessary.

D102E754

D

Negative rectifier test:
Inspect the open circuit for stator coil lead termi-
nals using the ohmmeter (2).
Replace the rectifier if necessary.
