Inspection

Inspect Starter Armature Assembly

5. Inspect outside diameter of commutator
Using vernier calipers, measure the outside diameter of the commutator.
 
HINT:
Commutator wear occurs due to the normal contacts with the brushes while turning.
If the measurement exceeds the specified wear limit, contact with the brush will be reduced, which will cause a reduction of current flow. As a result, starter output will be reduced or result in a complete stater failure.
