Re: voltmeter not reading

not reading anything? check the connections at the back of the gauge .either that or someone stole the battery out of it.

Re: voltmeter not reading

the gauge need a 12v feed and a ground. check under dash for anything loose or corroded

Re: voltmeter not reading

whats not working is the easiest way to tell. trim, bilge pumps, electronics, accessories.

It's very easy to check.
If your other gauges are working, you either have a bad gauge, or the 2 wires going to it are bad. Check with a DVM.
