VOLTMETER GAGE SHOWS NO INDICATION.

NOTE

Vehicle MASTER disconnect switch must be ON and ignition switch set to ON.

Failure to do so will cause erroneous results.

Refer to wiring diagram for all wiring repair steps.

Step 1.

Loosen two captive screws (1) and pull bracket (2) out enough to gain

access to area behind bracket.

Step 2.

Remove two clamps (3) and pipe assembly (4).

Step 3.

Check for +24 VDC between wire 121 (5) and ground at voltmeter

gage (6).

If +24 VDC is present, replace voltmeter gage (page 4-135).

If +24 VDC is not present, repair wiring 121 between voltmeter gage

and ignition switch.
