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.
Use a multimeter set on 200 ohms and 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 13-12, Page 13-9).
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.
