∆ CAUTION
• Never use emery cloth on the commutator. Particles of emery are conductive and may short-circuit
the commutator bars. Never 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 commu-
tator outside diameter is less than 1.535 inches (39 mm), replace the armature and bearings (Figure
12-12, Page 12-9).
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.
1. Using a multimeter set on 200
Ω
(ohms), place the positive probe on the commutator bars and the neg-
ative probe on the armature core. The reading should be NO continuity. If the reading is incorrect,
replace the armature and the two bearings (Figure 12-13, Page 12-10).
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.
