Brush Holder
1. Check the continuity across the brush holder and the holder
support with an ohmmeter.
2. If it conducts, replace the brush holder.
Armature Coil
1. Check the continuity across the commutator and armature coil
core with an ohmmeter.
2. If it conducts, replace the armature.
3. Check the continuity across the segments of the commutator
with an ohmmeter.
4. If it does not conduct, replace the armature.
