Starter Motor: Testing and Inspection
INSPECTION
1. ARMATURE
1. Check commutator for any sign of burns of rough surfaces or stepped wear. If wear is of a minor nature, correct it by using sand paper.
2. Run-out test
Check the commutator run-out and replace if it exceeds the limit.
3. Depth of segment mold Check the depth of segment mold.
4. Armature short-circuit test
Check armature for short-circuit by placing it on growler tester. Hold a hacksaw blade against armature core while slowly rotating armature. A
short-circuited armature will cause the blade to vibrate and to be attracted to core. If the hacksaw blade is attracted or vibrates, the armature,
which is short-circuited, must be replaced or repaired.
