Bench Testing: Stator
WARNING: This page is about a different car, the 2001 Lexus RX 300, 2001 Lexus LS 430, 2001 Lexus IS 300, and 2001 Lexus GS 430. However, it is still accessible from the selected car via links, so may be relevant.
Using ohmmeter, check continuity between stator leads. Continuity should exist between all stator leads. Check continuity between stator lead and generator housing. Continuity should not exist. If continuity is not as specified, replace stator.
