volt meter
« on: June 08, 2009 - 04:15:45 PM »
I have aftermarket volt/oil/ water temp guage, the volt quit working, is there a way to check the guage itself?  Battery is fully charged, where else should I look?

Scott,

  Do you have a voltmeter? If so, you can measure across the battery terminals with the engine running. You should see about 13.8 Volts. If not, then it's not your gauge that is at fault. This is the easiest test I can think of before you start taking the dash apart.

Mike, I do, the battery is good, I'm asking if I can test the guage? it is aftermarket triple guage set up, where do I start to find where the guage / reading is bad?

Check the voltage at the back of the gauge with a DMM or equivalent.

Assuming the guage has power to it / is connected still & has ground then the guage has failed

Disconnect one of the wires from the voltmeter. Attach a 9V battery across the gauge with some test leads. It should show 9 volts on the gauge.
