STARTING MOTOR-DIRECT DRIVE
(6) Crank the engine with a remote control starter
switch and observe the voltmeter reading. Voltmeter
reading should not exceed .3 volt. A voltmeter read-
ing of .3 volt or
less
indicates voltage drop is normal
in the cables, the starter relay switch, solenoid switch
and connections between the battery and starter motor
is normal. See "Starter Ground Circuit Test."
If
the voltmeter reading is more than
.3 volt, it in-
dicates high resistance in the starter insulated circuit.
Make the following tests to isolate the point of ex-
cessive voltage loss:
(A) Remove the voltmeter lead from the solenoid
connector and connect to the following points, re-
peating the test at each connection. The starter ter-
minal of the solenoid, battery terminal of the sole-
noid, battery cable terminal at the solenoid, starter
relay and the cable clamp at the battery.
(B) A small change will occur each time a normal
portion 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 insulated cable .2 volt
Solenoid switch .1 volt
Each Connection
.o
volt
Replace faulty cables. Clean and tighten all con-
nections.
Starter Ground Circuit Test
(1) Connect the voltmeter positive lead to the start-
er housing and the negative voltmeter lead to the
battery negative post.
(2)
Crank the engine with a remote control starter
switch and observe the voltmeter reading. The volt-
meter reading should not exceed .2 volt. A reading
of
.2
volt or less indicates voltage loss in the ground
cable and connections are normal. If the voltmeter
reading is more than .2 volt, it indicates excessive
voltage loss in the starter ground circuit. Make the
following tests to isolate the point of excessive voltage
loss, repeating the test at each connection.
(a) Starter drive housing.
(b)
Cable terminal at the engine.
