replace the armature.

8. Check with an ohmmeter that no continuity exists between the commutator (A) and armature coil core (B), and

between the commutator and armature shaft (C). If continuity exists, replace the armature.

INSPECT STARTER BRUSH

Brushes that are worm out, or oil-soaked, should be replaced.

STARTER BRUSH HOLDER TEST

1. Check that there is no continuity between the (+) brush holder (A) and (-) brush holder (B). If there is no continuity,

replace the brush holder assembly.

2. Pry back each brush spring (A) with a screwdriver, then position the brush (B) about halfway out of its holder, and

release the spring to hold it there.
