1981 Plymouth Champ LS, Automatic TransFACTORY OEM SERVICE PROCEDURE

Stator Test

NOTE: 100 amp. alternator 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.
  1. 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.
  2. If lamp lights, stator lead is grounded. On all but 100 amp. alternators, press test probe firmly on one phase terminal lead and touch second probe to each of the other 2 stator leads. Test lamp should light when probe contacts each terminal. If lamp does not light, stator is open.
