Armature Coil Test

WARNING: This page is about a different car, the 2004 Toyota RAV4 and 2003 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

Check for continuity between segments of commutator. See Fig 1. If continuity is not present between any segment, replace armature.
Using ohmmeter, check for continuity between armature coil core and commutator. See Fig 2. If continuity is present, replace armature.
