1. Disconnect the field coil wire from the "M" terminal of the magnetic switch.
SeeFig. 5
.
2. Connect a 12-volt battery between the "M" terminal and body.
3. Pull the pinion out and release. If the pinion quickly returns to its original
position, everything is operating properly. If it doesn't, replace the magnetic
switch. WARNING:Be careful not to get your fingers caught when
pulling out the pinion.
CAUTION: To prevent coil from burning, DO NOT apply voltage
to starter assembly for more than 10 seconds.

FREE RUNNING TEST 1. Place the starter motor in a vise equipped with soft jaws and connect a fully-
charged 12-volt battery to starter motor.
2. Connect a test ammeter (100-ampere scale) and carbon pile rheostat in series
between the positive battery terminal and starter motor terminal. See Fig. 6
.
3. Connect a voltmeter (15-volt scale) across the starter motor.
4. Rotate carbon
pile to full resistance
position.

5. Connect the battery cable from the negative battery terminal to the starter
motor body.
6. Adjust the rheostat until the battery positive voltage shown by the voltmeter is
11V.
7. Confirm that the maximum amperage is 95 amps, and that the starter motor
turns smoothly and freely.

COMMUTATOR CHECK 1. Place the armature on a pair of V- blocks and check the runout by using a dial
gauge. See STARTER SPECIFICATIONS
.
2. Check the outer diameter of the commutator. See STARTER
SPECIFICATIONS
.
3. Check the depth of the undercut between segments. See STARTER
SPECIFICATIONS
.
4. Replace commutator if runout, diameter or undercut depth is not within
specification.
BRUSH CHECK

Page 3543 of 3870
1. Check the brush for roughness of the surface that contacts the commutator and
check the brush length. Replace the brush holder if this measurement exceeds
the limit. The minimum limit is .28" (7.0 mm)
2. In the case contacting surface has been corrected or the brush has been
replaced, correct the contacting surface winding sandpaper around the
commutator. OVERRUNNING CLUTCH 1. While holding clutch housing, rotate the pinion. Drive pinion should rotate
smoothly in one direction, but should not rotate in opposite direction. See Fig.
7 . If clutch does not function properly, replace overrunning clutch assembly.
2. Inspect the pinion for wear or burrs. If pinion is worn or burred, replace the
overrunning clutch assembly. If pinion is damaged, also inspect the ring gear
for wear or burrs.

FRONT & REAR BRACKET BUSHING CHECK Inspect the bushing for wear or burrs. If the bushing is worn or burred, replace the
front bracket assembly or rear bracket assembly. ARMATURE CHECK 1. Check that the armature coil is not grounded.
2. Place armature in a growler. See Fig. 8
.
3. Hold a thin steel blade parallel and just above while rotating the armature
slowly in the growler. A shorted armature will cause a blade to vibrate and
attract to the core. Replace the shorted armature.
4. Check the insulation between the armature coil cores and the commutator
segments. They are normal if there is no continuity. See Fig. 9
.
5. Check for continuity between the segments. The condition is normal if there is
continuit
y. See Fig. 10
.
