Armature Coil
1. Check the continuity between the commutator and armature coil
core with an ohmmeter.
2. If it conducts, replace the armature.
3. Check the continuity between the segments of the commutator
with an ohmmeter.
4. If it does not conduct, replace the armature.

[2] ALTERNATOR
Bearing
1. Check the bearing for smooth rotation.
2. If it does not rotate smoothly, replace it.

Stator
1. Measure the resistance across each lead of the stator coil with
an ohmmeter.
2. If the measurement is not within the factory specification,
replace it.
3. Check the continuity across each stator coil lead and core with
an ohmmeter.
4. If infinity is not indicated, replace it.

Rotor
1. Measure the resistance across the slip rings with an ohmmeter.
2. If the resistance is not the factory specification, replace it.
3. Check the continuity across the slip ring and core with an
ohmmeter.
4. If infinity is not indicated, replace it.
