NOTE
• Measure the
diameter
of the commutator.
*
Replace the starter motor with a new one if the
commutator diameter is less than the service limit.
OEven if the foregoing checks show the armature to be
good. it may be defective in some manner not readily
detectable with an ohmmeter. If all other starter motor
and starter motor circuit components check good. but
the starter motor still does not turn over or only turns
over
weakly.
replace the starter motor w
ith
a new
one.

Armature Inspection
Using
the x 1
n
ohmmeter
range,
measure the resist-
ance between any two commutator
segments.
*
If there is a
high
resistance or no reading (00) between
any two
segments,
a
winding
is open and the starter
motor must be replaced.
.Using the highest
ohmmeter
range, measure the
resist-
ance between the segments and the shaft.
*
If there is any reading at all, the armature has a short and
the starter motor must be
replaced.
