For 1990-2009 cars only
Inspection Procedure
- Inspect the insulation between commutator and armature coil using the voltmeter.
- Replace the armature assembly if necessary.
- Ground test the armature for armature coil.
- Short circuit test the armature for armature coil.
- Check the continuity between the commutator bars using multimeter.
- Replace the armature assembly if necessary.
- Open circuit test the armature for armature coil.
- Inspect the brushes, the pop-out springs, and the brush holder for wear (wear limit [a]) and damage. Replace the brushes, if necessary.
Important: If test equipment is available, check the armature for short circuit by placing it on a growler, and holding back a saw blade over the armature core while the armature is rotated. If the saw blade vibrates, replace the armature.
