Starter Motor: Initial Inspection and Diagnostic Overview
Armature Open Circuit Inspection
An open circuit in the armature can sometimes be detected by examining commutator for signs of burning. A spot burned on the commutator is caused by
an arc formed every time a commutator segment connected to the open circuit winding passes under a brush.
Pinion Inspection
Pinion Travel Check
1. Using two switches and a battery, connect starter as shown.
2. When switches K1 and K2 are closed the starter drive will be forced outward and the motor will run. If switch K2 is opened, the starter will stop
turning with the pinion in the full out position.
3. Check pinion end gap in this position. End gap should be 0.004-0.100 inch.
