MOTOR
Visual Inspection, Continued:
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 Ω (ohms), place one probe on the commutator and the other on the armature
core. The multimeter should indicate no continuity (Figure 15-7, Page 15-6). If the reading is incorrect,
replace the armature.

FIELD WINDINGS INSPECTION

Burned or scorched insulation on the field windings indicates the motor has overheated due to overloads or
grounded or shorted coil windings. If the insulation on the field windings is scorched, replace the motor or the
stator shell assembly.
