Voltmeter acting weird
I hooked up a autometer voltmeter the other day and it worked fine for a day, today i drove the car and it was working fine, turned it off and it had stopped working. so long story short i removed it tested it on a batt. it worked ok, then cleaned the ground plugged it back up and it began to read 12volts. I then re installed it got everything hooked back up and it does nothing again!!
I have it hooked up to the radio acc wire, its still hooked up radio works and everything, i do have the gague and the gauge light grounded to the same spot. the light still works fine but the gauge is dead again. Any suggestions? Its got to be a wire i would think but there all still tight and hooked up.
