Starter Armature: Testing and Inspection
Armature Open Circuit Test
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 the commutator segment, connected to the open circuit winding, passes under a brush.
