CAUTION
• Do not use emery cloth on 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.
2. Using a micrometer, measure the outside diameter at two points along the commutator. If the commutator outside
diameter is less than 1.60 inches (40.6 mm), replace the armature and bearings
(Figure 20-11, Page 20-7) .
ARMATURE GROUND TEST
CAUTION
• Do not submerge armature in solvent.
NOTE: Before testing, wipe the armature with a clean cloth and remove carbon dust and metal particles from between
commutator bars.
Using a multimeter set on 200 (ohms), place the positive (+) probe on the commutator bars and the negative (–) probe
on the armature core. The reading should be no continuity. If the reading is incorrect, replace the armature and the
two bearings
(Figure 20-12, Page 20-8) .

VISUAL INSPECTION OF FIELD COILS
If the insulation on the field coils appears blackened or charred, the serviceability of the coils is questionable. Burned
or scorched coil insulation indicates the starter/generator has overheated due to overloads or grounded or shorted coil
windings. Be sure the insulators are tight in the housing.
