Measure Commutator Insulation Depth
Measure the depth of the insulating material
(Figure 10-14, (1)) between commutator segments
(Figure 10-14, (2)). If the depth measures less
than the limit, use a hacksaw blade
(Figure 10-14, (3)) to remove the insulating
material until the depth is within the limit. See
Starter Motor Specifications on page 10-6 for
service limit.
A normal commutator condition is indicated in
(Figure 10-14, (4)). An abnormal commutator
condition is indicated in (Figure 10-14, (5)).

Armature Coil Continuity Test
Check for continuity between the commutator
segments using a multimeter (Figure 10-15). The
multimeter should indicate continuity.
If the multimeter does not indicate continuity,
replace the armature.

Armature Coil Insulation Test
Check for continuity between a commutator
segment and the shaft or armature using a
multimeter (Figure 10-16). The multimeter should
not indicate continuity.
If the multimeter indicates continuity, replace the
