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

Armature Ground Test
ý
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 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 12-12, Page 12-8).
