BRUSHES

1. Replace brushes if worn to limit. (Scheme 46) Replace all brush springs if any springs are damaged or corroded.
2. To remove brushes from holder, unsolder pigtail from terminal. (Scheme 47) To replace, install brush into the brush holder and solder lead wire.

ROTOR

1. Check Rotor Coil For Continuity - Check to make sure that there is continuity between the slip rings. (Scheme 48) Resistance should be 3.1 ohms. If resistance is extremely low, there is a short. If there is no continuity or if there is a short, replace generator. See «GENERATOR»(ref-168064-S00638544742004102900000) under REMOVAL & INSTALLATION.
2. Check Rotor Coil For Ground - Check to make sure that there is no continuity between the slip rings and the rotor shaft. (Scheme 49) If there is continuity, replace generator. See «GENERATOR»(ref-168064-S00638544742004102900000) under REMOVAL & INSTALLATION.

STATOR

Check Stator Coil For Grounding - Check to make sure that there is no continuity between the coil and generator housing. (Scheme 50) If there is continuity, replace the generator.
