Armature Ground Test
CAUT ION
• 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. Use a multimeter set on 200 ohms and 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 12-12, Page 12-7) .
Visual Inspection of Field Coils
Burned, blackened, charred or scorched coil insulation indicates the starter/generator has overheated due to
overloads, grounding or shorted coil windings and should be replaced. Be sure the insulators are tight in the
housing.
