Field Coil
1. Check the continuity across the lead (1) and brush (2) with a
circuit tester.
2. If it dose not conduct, replace the yoke assembly.
3. Check the continuity across the brush (2) and yoke (3) with a
circuit tester.
4. If it conducts, replace the yoke assembly.

(8) Alternator
Bearing
1. Check the bearing for smooth rotation.
2. If it does not rotate smoothly, replace it.
W1019790
Stator
1. Measure the resistance across each lead of the stator coil with
resistance range of circuit tester.
2. If the measurement is not within factory specification, replace it.
3. Check the continuity across each stator coil lead and core with
resistance range of circuit tester.
4. If infinity is not indicated, replace it.

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