make test connections to the solenoid switch termi
nal and to ground to test the hold-in winding (fig.
1F-6). Use the carbon pile rheostat across the bat
tery to decrease the battery voltage to the value
listed in specifications. Compare the current flow
with the value listed in Specifications. A high cur
rent flow indicates a shorted or grounded hold-in
winding, and a low current flow indicates excessive
resistance.

To test the pull-in winding, connect the battery
across the solenoid switch (S) terminal and the Sole
noid motor (M) terminal. To reduce the voltage to
the specified value, connect the carbon pile rheostat
between the battery and M-terminal as shown with
dashed lines (fig. 1F-6) instead of across the battery
as shown with solid lines. If not needed, connect a
jumper directly from the battery to the M-terminal.
STARTING SYSTEMS 1F-7
CAUTION: To prevent overheating, do not allow the
pull-in winding to be energized more than 15 seconds.
The current flow will decrease as the winding temper
ature increases.
• Overrunning Clutch—Test the overrunning clutch
action. The pinion gear should turn freely in the
overrunning direction. Inspect the pinion gear teeth
to ensure that they have not been chipped, cracked,
or excessively worn. Replace assembly if necessary.
Badly chipped pinion gear teeth indicate possible
chipped teeth on the ring gear. The ring gear should
be examined and replaced if necessary.
Test the overrunning clutch for slipping with the
clutch attached to the armature. Wrap the armature
with a shop towel and clamp in a vise. Using a 12-point
deep socket and torque wrench, place the socket on the
clutch and turn counterclockwise. The clutch should not
slip with up to 50 foot-pounds (68 N»m) torque applied.
If it does, replace the clutch.
Assembly
(1) Position clutch assembly on armature shaft. To
replace snap ring and retainer onto armature:
(a) Position retainer on armature shaft with
cupped surface facing snap ring groove.
(b) Position snap ring on end of shaft. With
piece of wood on top, force ring over shaft and tap in
place (fig. 1F-7), then slide ring down into groove.
