Stator Test
NOTE:
On 114-amp alternators, stator windings are "Delta" wound, and cannot be checked with common shop equipment. If stator is not grounded, and all other components check correctly, suspect an open or a short in stator.
- Separate stator from both end shields. Press ohmmeter lead firmly onto any bare spot on frame. Press ohmmeter lead firmly to each of the 3 phase lead terminals, one at a time. See Fig 1. If zero or low resistance is measured, stator lead is grounded.
- Press ohmmeter lead firmly on one phase lead, and contact each of the other 2 stator leads. If no continuity exists, stator is open. Install a new stator if it is open or grounded.
