(8) 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
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.
Resistance Factory specification
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.
Resistance Factory specification
Slip Ring
1. Check the slip ring for score.
2. If scored, correct with an emery paper or on a lathe.
3. Measure the O.D. of slip ring with vernier calipers.
4. If the measurement is less than the allowable limit, replace it.
Factory specification
Slip ring O.D.
Allowable limit
Brush Wear
1. Measure the brush length with vernier calipers.
2. If the measurement is less than allowable limit, replace it.
3. Make sure that the brush moves smoothly.
4. If the brush is defective, replace it.
