h.
Connect negative (black) lead from multimeter to test connector pin 4.
CAUTION
DO NOT crank starter motor for more than 30 seconds at a time. After 30 seconds, allow starter motor to
cool for at least two minutes before attempting to start engine again. Excessive heating of starter motor may
result in damage or premature starter failure.
NOTE
Tachometer will indicate no more than 400 RPM for this test.
i.
Using key start switch, crank engine and observe multimeter for an indication of more than 0.45 volts. If indication
is more than 0.45 volts, replace starter relay (WP 0045 00).
j.
Remove test leads from test connector.
k.
Install test connector protective cap.
l.
Connect wire to upper terminal (GND Negative) on engine fuel shutoff solenoid.
11.
Starter Solenoid Voltage Test.
NOTE
This test measures voltage drop across starter solenoid contacts.
a.
Ensure engine is OFF.
b.
Place battery disconnect switch in ON position.
c.
Turn all accessories OFF.
d.
Remove fuel pump fuse (WP 0040 00) to shut OFF fuel supply (engine should crank, but not start).
e.
Remove protective cap from test connector.
f.
Select VDC on multimeter.
g.
Connect positive (red) lead from multimeter to test connector pin 1.
h.
Connect negative (black) lead from multimeter to test connector pin 2.
CAUTION
DO NOT crank starter motor for more than 30 seconds at a time. After 30 seconds, allow starter motor to
cool for at least two minutes before attempting to start engine again. Excessive heating of starter motor may
result in damage or premature starter failure.
NOTE

i.
Using key start switch, crank engine and observe multimeter for an indication of more than 0.75 volts. If indication
is more than 0.75 volts, replace starter (WP 0035 00).
j.
Remove test leads from test connector.
k.
Install test connector protective cap.
l.
Connect wire to upper terminal (GND Negative) on engine fuel shutoff solenoid.
