BRUSHES
Measure the length of both brushes with a vernier caliper. (Scheme 29) If either brush is shorter than the service limit, replace the rear housing assembly. If brush length is OK, go to ROTOR SLIP RING.
Scheme 29
ROTOR SLIP RING
- Check that there is continuity between the slip rings. If there is continuity, go to next step. If there is no continuity, replace the rotor assembly. (Scheme 30)
- Check that there is no continuity between each slip ring and the rotor and the rotor shaft. If there is no continuity, replace the rear housing assembly, and go to «ALTERNATOR»(ref-153319-S21963341632004060800000) under OVERHAUL. If there is continuity, replace the rotor assembly.
