• Do not submerge the armature in solvent.
NOTE: Before testing the armature, wipe it clean with a clean cloth. Remove any carbon dust and metal
particles from between the commutator bars.
1. With a multimeter set to 200 ohms, place one probe on the commutator and the other on the armature
core. The multimeter should indicate no continuity (Figure 16b-12, Page 16b-8) . If the reading is incor-
rect, replace the armature.

or grounded or shorted coil windings. If the insulation on the field windings is scorched, replace the motor
or the stator shell assembly.
