Volt meter question
I have a 74 Chevy C20 pickup. The Volt meter doesn't work while installed in the truck. However it works perfect out of the vehicle when measuring battery voltage. There are only 2 plug-in points for it in the instrument cluster but the gage has 3 terminals. What is the purpose of the third terminal? I am confused.
