The Camaro Amp Gauge Mystery

The Camaro in 1967-1969 came with the highly desirable option of the Console gauges. The one gauge which has always been a little weird to us here at Midnight Oil is the Camaro amp gauge. The amp gauge (sometimes referred to as the battery gauge) is super easy to wire up. But, you get it wrong and POOF! Now you need a new amp gauge. We thought we would write this post for those who are having trouble with their Camaro amp gauge. This info is not just about the 1967-69 Camaro. It will help you diagnose almost any early GM amp gauge because the wiring colors are the same.

Wire it up!

The wiring on the back of the amp gauge goes like this:

With the gauge upright; there are two terminals one at 12 o’clock and one at 6 o’clock.

  • 12 o’clock gets the black wire coming from the battery junction block (Just because the wire is black does not mean it is a ground!)
  • 6 o’clock gets the black wire (with white stripe) coming from the horn relay.

BOTH of these wires MUST BE hot. The amp gauge’s job is to read the amperage traveling through this circuit. If you have hooked the amp gauge up with a hot and a ground and turned on the ignition, you will need to replace the amp gauge because you have just fried its insides.

Running your own wires in series i.e. battery to gauge to alternator is a bad thing. This will fry the gauge period. The amp gauge was designed to be run parallel to the alternator circuit.

If the needle won’t move at all…give the gauge the sniff test. You will probably smell that ozone burned wire smell and you will need to replace the gauge. That is pretty much it. Not much to the Amp gauge circuit.

I’m Fried…Now What?

Midnight Oil sells single, new reproduction console gauges just in case you have fried yours. We have the 1967 Camaro amp gauge and the 1968-69 Camaro amp gauge ready to ship today! If you have any questions, don’t hesitate to drop us an email or call!
