1) Check continuity across rotor slip rings. Resistance should be 3-5 ohms. Replace rotor if continuity is not present or resistance is not within specification. 2) Check continuity between individual slip rings and rotor shaft. If continuity is present, rotor coil or slip ring is grounded. Replace rotor. STATOR Ensure continuity is not present between stator coil leads and stator core. Check continuity between leads of stator coil. If continuity is not present between coil leads, replace stator. OVERHAUL Replace brushes if worn to limit line. Limit line is line closest to rotor contact end of brush. Brushes can be retained in brush holder while installing rotor by inserting wire into back of rear housing. See Fig. 3.
