Rotor: Testing and Inspection
ROTOR1. Check the rotor coil for continuity. Make sure there is continuity between the slip rings. If resistance is extremely low, there is a short. If there is no continuity or if there is a short circuit, replace the rotor assembly.
Resistance value: Approx. 3.1 Ohms
2. Check the rotor coil for a ground. Check that there is no continuity between slip the ring and the core. If there is continuity, replace rotor assembly.
