SEV MOTOROLA Alternators: Overhaul: Testing: Stator

Check stator for short-circuiting. If one or more of the coils are burned, there must be a short-circuit in stator. Connect test lamp (12 volt, 2-5 watt) between stator plates and a terminal on stator (see Figure). If lamp lights, isolation between stator winding and stator plates must be burned, in which case stator should be replaced.
