Stator Test
1982 Plymouth Horizon Base, 2.2L Eng VIN B, Standard TransSECTION Stator Test
NOTE:
114 amp. alternators can be checked for stator grounds only. Due to its "Delta" windings, it cannot be checked for opens or shorts with common automotive shop equipment. If stator is not grounded and all other components check correctly, suspect either an open or short in stator.
- Separate stator from both end shields. Press one test probe firmly against any clean spot (varnish removed) on stator frame. Stator must be bare and clean. Press other probe firmly to each of the 3 phase lead terminals, one at a time.
- If lamp lights, stator lead is grounded. On all but 114 amp. alternators, press test probe firmly on one phase terminal lead and touch second probe to each of the other 2 stator leads, one at a time. Test lamp should light when probe contacts each terminal. If lamp does not light, stator is open.
