Rotor Assembly Check
- Check outside circumference of slip rings for roughness or foreign materials. Replace slip ring if badly worn or if roughness is noted.
- Using an ohmmeter, connect leads to field coil and slip ring. Continuity should exist. If not, field coil is defective. Replace rotor assembly.
- Connect ohmmeter leads to slip ring and rotor shaft. If there is continuity, slip ring is grounded. Replace rotor assembly.
