I recently purchased a 69 and the voltage gauge reads about 14.5 when the car is running. The problem is it reads 12 when the ignition is off and the key removed. Shouldn't the gauge go to zero with the ignition off? What is wrong? Is it wired wrong or is this the norm. Thanks for any and all help.

Voltage gauges aren't stock in a first generation camaro, so a previous owner added it. Gauge should drop to zero with the key off. Sounds like he (or she) wired it directly to the battery or some other always hot power source instead of a switched source.

Normally (for cars that have volt guages), a voltage guage is wired to IGN power. This way you can see the cranking voltage of the electrical system. If ACC power is used, the voltage guage will go to zero during crank.

I wired mine direct to the cigarette lighter wire, which is hot all the time. There is nothing wrong with having the voltmeter read all the time.
