- Inspect slip ring brush contact surface. If surface is worn or rough, smooth surface with fine Emory paper. Measure slips ring diameter. See SLIP RING DIAMETER table. If diameter is not as specified or brush contact surface is excessively worn or damaged, replace slip rings and/or rotor.
- Resistance across rotor slip rings should be about 3 ohms. If resistance is not as specified, replace rotor. Check continuity between each slip ring and rotor core/shaft, individually. Continuity should not exist. If continuity exists, rotor coil and/or slip ring is grounded. Replace rotor.
