MOTOR COMPONENT TESTING AND INSPECTION

See General Warnings on page 1-1.

ARMATURE INSPECTION AND TESTING

1. Remove the motor from the vehicle. See Motor Removal, Section 16, Page 16-2.
2. Remove the end cap and armature by performing steps 1 through 6 of Motor Disassembly on page 16-4.
Visual Inspection
• Burned, charred or cracked insulation
• Improperly cured varnish
• Thrown solder
• Flared armature windings
• Damaged armature core laminations
• Worn, burned or glazed commutators
• Dirty or oily commutators
• Raised commutator bars
• Worn armature bearing or shaft
A dirty or oily commutator should be cleaned and wiped dry. Abnormalities identified during the inspection can help
determine original cause of failure. Slight roughness of the commutator can be polished smooth with 400 grit or
finer sandpaper. See following CAUTION and NOTE.
CAUTION
• Do not use emery cloth to polish the commutator. Particles of emery are conductive and may
short-circuit the commutator bars. Do not use oil or lubricants on the commutator or brushes.
NOTE: Oil on the commutator may indicate a faulty transaxle input shaft oil seal.
Armature Ground Test
CAUTION
• Do not submerge the armature in solvent.
NOTE: Before testing the armature, wipe it clean with a clean cloth. Remove any carbon dust and metal particles from
between the commutator bars.
1. With a multimeter set to 200 ohms, place one probe on the commutator (1) and the other on the armature
core (2). The multimeter should indicate no continuity (Figure 16-10, Page 16-8). If the reading is incorrect,
replace the armature.
