(c) Cable clamp at the battery.
A small change will occur each time a normal por-
tion of the circuit is removed from the test. A definite
change in the voltmeter reading indicates that the
last part eliminated in the test is at fault.
Maximum allowable voltage loss is as follows:
Battery ground cable
.o
volt
Engine ground circuit .2 volt
Each connection .1 volt
REMOVAL OF STARTING MOTOR
(1) Disconnect the ground cable at the battery.
(2) Remove the starter cable at the starter.
(3) Disconnect the solenoid lead wire from the sole-
noid.
(4) Remove the bolts attaching the starting motor
to the flywheel housing and remove the starter motor
and housing removable seal.
TESTING THE STARTING MOTOR
(Bench
Test)
Free Running Test
(1) Place the starter in a vise equipped with soft
jaws and connect a fully-charged, 12 volt battery to
the starter as follows:
(2) Connect a test ammeter (100 amperes scale)
and a carbon pile rheostat in series with the battery
positive post and starter terminal.
(3) Connect the voltmeter (15 volt scale) across the
starter.
(4) Rotate the carbon pile to the full-resistance po-
sition.
(5) Connect the battery cable from the battery n e g
ative post to the starter frame.
(6)
Adjust the rheostat until battery voltage shown
on voltmeter reads 11 volts.
(7) The current draw should
be 78
amperes maxi-
mum at 3800 minimum rpm.
Locked
Resistance Test
(1) Install the starting motor in test bench.
(2)
Follow the instructions of the test equipment
manufacturer and test the locked-resistance of the
starter against the following specifications.
(3) With applied battery voltage adjusted to 4 volts;
the current draw should be 350 amperes.
DISASSEMBLING THE
STARTING MOTOR
(1) Refer to Figure 1, remove the through bolts
and tap the commutator end head from the field
frame.
