MALFUNCTION
—
TEST OR INSPECTION
CORRECTIVE ACTION
6.
VOLTMETER IN RED (OVERCHARGE) ZONE (Ml 010 AND Ml 028 WITH 200 amp SYSTEM)
—
Step 1.
Perform Electrical Troubleshooting malfunction #5, step 11.
STARTING SYSTEM
7.
ENGINE STARTS BUT WILL NOT CONTINUE TO RUN AT IDLE
Step 1.
Turn key to “RUN” position. Check for voltage at fast idle solenoid.
If there is voltage and fast idle solenoid plunger does not extend, replace fast
idle solenoid. (See TM 9-2320-289-20)
If there is no voltage, perform step 2.
Step 2.
Disconnect connector from cold advance switch at right rear of engine block. (See
wiring diagram E-3 or E-5) Jump light green and pink/black leads at connector,
Check for voltage at fast idle solenoid.
If there is voltage and fast idle solenoid plunger does not extend, replace fast
idle solenoid. (See TM 9-2320-289-20)
If there is voltage, fast idle solenoid plunger extends, and engine is cold,
replace cold advance switch.
If there is voltage, fast idle solenoid plunger extends, and engine is hot,
system operates properly.
If there is no voltage, trace circuit. (See wiring diagram E-3 or E-5)
WINDSHIELD WIPER/WASHER SYSTEM
8. WIPER MOTOR INOPERATIVE IN ONE SPEED
Step 1.
Turn key to “ RUN” position, Turn wiper switch to inoperative speed position,
Connect jumper wire from gray lead terminal on wiper motor to ground (if low
speed inoperative) or from double white lead terminal on wiper motor to ground (if
high speed inoperative).
If wiper motor runs, trace circuit from wiper motor to switch. (See wiring
diagram E-20 or E-21)
If wiper motor does not run, remove end cap assembly from wiper motor.
(See paragraph 10-8) Inspect brushes for damage. Replace any damaged
brushes in end cap assembly.
