Inspection & Repair: Rotor
- Apply tester to slip rings of rotor. If ohm reading is within 4-5 ohms, rotor continuity is satisfactory. If not, an open connection to the field coil may exist.
Touch probes to each slip ring; then to rotor core and each slip ring .
- Next, apply probes to slip ring and rotor core to check for ground. If continuity exists, replace rotor assembly.
