See Test Procedure 8 – Starter/Generator (Starter Function) on

Visual Inspection of Armature
Obvious defects can be seen by examining the armature. If an armature has frayed or charred insulation, bro-
ken wires or thrown solder, it is obvious without testing that it should be replaced. Faults seen during the
visual inspection can aid in diagnosing the original cause of the failure. Items to look for are listed below.
•
Burned, charred, or cracked insulation
•
Improperly cured varnish
•
Thrown solder
•
Flared armature windings
•
Worn, burned, or glazed commutator
•
Loose or raised commutator bars
•
Bruised or damaged armature core laminations
•
Worn armature bearing or shaft
•
Dirty or oily commutator
