Volt gauge

[REDWOLF]

Volt gauge not working. Replaced gauge and still not working. Help please.

There are two fuses and a relay that control the voltmeter.

First fuse is the 24v fuses that feeds the voltmeter and is controlled by the relay. Second is the 12v ignition fuse. When the key is on it feeds 12v for the relay to energize and send the 24v to the meter.

The voltmeter relay is under the center dash. It is next to the starter and GEN2 relays.

Also the 300 ohm resistor on the voltmeter has to be in working condition.

Where are the fuses? Close to the relay?

Fuse #12 and #15 in the fusebox.

you can find the fusebox diagram in the TMs, the CUCV FAQ thread or the CUCV Fusebox Layout thread that is listed in the CUCV Helpful Threads sticky.

Also the TM 9-2320-289-20 tech manual has a step by step troubleshooting section for a non-working voltmeter.

Thanks.

I thought it was 3 ohm

The voltmeter resistor is 300 ohm. Many threads that discuss it.

I had read them. Just had been a wile. Could not reminder. Thanks.
