Bench Testing: Rotor

Using a DVOM, check for continuity between rotor slip rings. Ensure continuity is present. Replace rotor assembly if continuity is not present. Check for continuity between any rotor slip ring and rotor core. Continuity should not be present. Replace rotor assembly if continuity is present. Ensure slip ring outer diameter exceeds minimum specification. See SLIP RING MINIMUM OUTER DIAMETER  table.
