Troubleshooting - Continued

(c) Since the voltmeter reads 24 vdc, disconnect circuit 82 at the

engine disconnect.

Measure the voltage of circuit 82 from the engine

disconnect plug pin E and pin B to ground.

The voltmeter should read 24

vdc.

(d) Since the voltmeter reads 24 vdc, disconnect the starter motor

ground circuit at the engine disconnect.

Measure the resistance of the

ground circuit from the engine disconnect plug pin E and pin B to the

vehicle chassis. The ohmmeter should read zero Ohms.

(e) Since the ohmmeter reads zero Ohms, measure the resistance of the

starter motor ground circuit from the ground terminal of the starter motor

to pin E and pin B of the engine disconnect receptacle. The ohmmeter should

read zero Ohms.

(f) Since the ohmmeter reads zero Ohms, measure the resistance of

circuit 82 from the engine disconnect receptacle pin B and pin E to circuit

82 terminal on the starter solenoid. The ohmmeter should read zero Ohms.

(g) Since the ohmmeter reads zero Ohms, measure the resistance from the

ground terminal on the starter motor to the ground terminal on the starter

solenoid. The ohmmeter should read zero Ohms.

(h) Since the ohmmeter reads zero Ohms, inspect the interconnecting bus

bar from the starter motor to the starter solenoid for security and

tightness on the terminals.

(i) Since the bus bar is secure and tight, reconnect all engine

disconnect plugs.

Disconnect the starter-module plug.

Depress the START

switch (figure 28, view C, on page 66) and at the same time measure the

voltage from the starter-module plug pin A to ground. The voltmeter should

read 24 vdc.

(j) Since the voltmeter reads 24 vdc, measure the voltage from the

starter-module plug pin B to ground. The voltmeter should read 24 vdc.

(k) Since the voltmeter reads 24 vdc, disconnect circuit 82 at the

engine disconnect. Measure the resistance from the bus bar terminal on the

starter motor to the engine chassis. The ohmmeter should read zero Ohms.
