Rotor

Fig. 6 Alternator Rotor Resistance Limits:

1. Check rotor for continuity. Ensure that there is continuity between slip rings.
2. If resistance is not as shown in Fig. 6, there is a short in the rotor. If no continuity exists or if there is a short, replace rotor assembly.
3. Ensure that there is no continuity between slip ring and core. If continuity exists, replace rotor assembly.
