Voltmeter ohm test

Is there an ohms test for the voltmeter. Mine suddenly stopped working. The battery is charging normally at 14+ volts when running. I am getting a ohms reading on the gauge wires but nothing across the voltmeter terminals.

I have not seen a similar post. Thanks for your thoughts!

I'll have to test mine.

There is a zener diode inside that will make the measurement dependent upon what way you hook up the test leads.

Does your meter have a diode test?

Found my tester that will test diodes. Checked the voltage reading on the connectors/leads to the gauge and the reading is in the normal range with the ignition on. Its the gauge. is it repairable? I would like to keep the OEM if I can.

I never really tried to repair one of those.

Depending upon how much you are really attached to that gauge, there are companies out there that do repair them.
It probably won't be cheap.

Ok now after checking it out, testing wires and grounds, it starts working 5 minutes after start-up. Goofy. I know the ground is good as it has been tested and i grounded the dash thoroughly in the past. I need to get a wire pipe cleaner into the connectors i guess...

Mine just recently stopped working properly and I am not happy.
Two or so years ago that little gauge told me something was wrong during a good rain when I was forty five miles out in the boonies .
The battery barely got me home without the head lights on after dusk, no constant windshield wipers, or I never would have made it.
