d.
following is a typical procedure that unit maintenance personnel should follow in
performing troubleshooting and fault isolation of this vehicle's starting/charging
system malfunction.
Step 1.
This step is performed similar to step 1 for the malfunction: STARTER
FAILS TO CRANK ENGINE, found in paragraph 6b on page 7. In this case, however, the
volt gage indicator is pointing to the red zone.
Step 2.
Because the volt gage indicator is in the red zone, use a multimeter
and measure the voltage between the positive (+) terminal (1)(figure 4 on the
following page) and ground; the voltmeter should read 30 volts.
Step 3.
The multimeter indicates no voltage reading between the positive
terminal and ground, this is an indication that the volt gage is defective.
Therefore, replace the vehicle volt gage as described in the following
subparagraph.
e.
Replacing the Volt Gage.
The following is the procedure that the unit
personnel would follow in replacing the vehicle volt gage.
Step 1.
Remove lamp socket (1a)(figure 4 on the following page) from the back
of the volt gage (9).
Step 2.
Remove negative lead 1W10-M1 (1b) by removing the nut (3) and
lockwasher (4) from the negative terminal (2). Tag the lead to prevent confusing
it with the other leads.
Step 3.
Remove positive lead 1W10-M1 (5) by removing the nut (7) and lockwasher
(8) from the positive terminal (6). Tag the lead to prevent it from being confused
with the other leads.
