Visual Inspection of Armature
WARNING
• WHEN MAKING ELECTRICAL TESTS OR REPAIRS, ALWAYS:
- WEAR SAFETY GLASSES OR APPROVED EYE PROTECTION.
- REMOVE THE KEY.
- PUT THE FORWARD AND REVERSE SWITCH IN NEUTRAL.
- DISCONNECT THE BATTERY AS SHOWN (FIGURE 12-1, PAGE 12-2).
• FOLLOW ALL PROCEDURES EXACTLY AS INSTRUCTED.
• SEE THE SAFETY WARNINGS ON PAGE 12-1.
Obvious defects can be seen by examining the armature. If an armature has frayed or charred insulation,
broken 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.
Slight roughness of the commutator can be polished away with 400 or finer sandpaper.
