2. Measure the length of the brushes with a vernier caliper.
Alternator Brush Length:
Standard: 10.5 mm (0.41 in)
Service Limit: 1.5 mm (0.06 in)
If the brushes are less than the service limit, replace the alternator brush assembly.
Rotor Slip Ring Test
1. Check the resistance between the slip rings.
There should be 2.9 ohms.
-
If resistance meets the specification, go to step 2.
-
If resistance does not meet the specification, replace the alternator.
2. Check that there is no continuity between the slip rings and the rotor or rotor shaft.
3. If the rotor fails either continuity check, replace the alternator.
