(b) Inspect the resistance of the commutator.
(1) Using an ohmmeter, measure the resistance
between the segments of the commutator.

If the resistance is not as specified, replace the
starter armature assembly.
(2) Using an ohmmeter, measure the resistance
between the commutator and armature coil
core.

Tester connection
If the resistance is not as specified, replace the
starter armature assembly.
(c) Using vernier calipers, measure the commutator
depth.
Specified depth:
3.1 mm (0.122 in.)
Maximum depth:
3.8 mm (0.150 in.)
If the depth is greater than the maximum, replace
the starter armature assembly.
INSPECT STARTER COMMUTATOR END FRAME
ASSEMBLY
(a) Check the brush length.
(1) Using vernier calipers, measure the brush
length.
Specified length:
9.0 mm (0.354 in.)
Maximum length:
4.0 mm (0.157 in.)
If the length is less than the minimum, replace
the starter commutator end frame assembly.
(b) Check the resistance.
(1) Using an ohmmeter, measure the resistance
between the positive (+) and negative (-)
brushes.
Resistance:
10 kΩ or higher
If the resistance is not as specified, repair or
replace the starter commutator end frame
assembly.
