Section 07 ELECTRICAL SYSTEM
Subsection 03 (STARTING SYSTEM)
Test the Armature for Open Circuit
Use growler test probes. Place one test probe
on a commutator bar and the other test probe
on the neighboring bar. Repeat this operation for
all bars, moving one test probe at a time. If the
growler lamp does not turn on, the armature cir-
cuit between these 2 bars is opened. The arma-
ture should be replaced or repaired; open circuits
most often occur at the commutator riser where
coils are soldered. (Burnt commutator bars are
usually an indication of an open-circuit armature
coil).
Brush Holder
Check the brush holder for insulation using
growler test probes. Place one test probe on the
insulated brush holder and the other test probe
on the brush holder plate. If the growler lamp
turns on, the brush holder has to be repaired or
replaced.
Brush Length
Measure brush length. If less than the specified
value, replace them.

Overrunning Clutch
The pinion of the overrunning clutch should turn
smoothly in a clockwise direction, and should not
slip in a counterclockwise direction. If defective,
replace.
Check the pinion teeth for wear and damage. If
defective, replace.
Relay
Inspect connections and clean as necessary. Re-
lay condition can be checked with an ohmmeter.
Install test probes on large connectors of relay
when it is activated ((+) on RED/GREEN wire and
(-) on relay body for the fan cooled models and (-)
on the BLACK wire for liquid cooled models).
IMPORTANT: No current must be present on large
cables when using ohmmeter, otherwise meter
could be damaged.
STARTER ASSEMBLY
Reverse the order of disassembly to reassemble
starter. However, attention should be paid to the
following operations.
Prior to assembling, coat sliding surfaces on arma-
ture shaft splines, overrunning clutch and bushing
with synthetic grease (P/N 413 711 500).
After placing collar no. 3 on armature shaft no. 11,
fit new snap ring no. 2 on armature shaft, then
make sure that it is properly secured.
Slide collar no. 3 over snap ring no. 2 and secure
in place by punching it at two or three places.
