32.4.1 Inspecting the magnetic switch
Check the magnetic switch for continuity between
terminal S and M, and between terminal S and body. If
zero-ohm is indicated (as an evidence of short circuit),
replace the magnetic switch.
32.4.2 Inspecting the armature
1. Check the armature with a growler tester. If short-
circuited, replace the armature. Also, check for
insulation between the commutator and its shaft.
Replace the armature if there is continuity.
2. Measure the outside dimension of the commutator
and the depth of undercut. Repair or replace if
exceed the service limit. Also, check the
commutator outside surface for dirtiness and
roughness. If it is rough, polish the commutator
with fine-grain sandpaper.
32.4.3 Brush holder inspection
1. Check the brushes. If worn out nearly to the
service limit, replace the brushes.
2. Check the brush spring tension. If any defect is
found, replace springs.
3. Check for insulation between the positive brush
holder and holder base. If there is continuity,
replace the holder assembly. Also, check the brush
holder if itís firmly coaking the brushes.
