How Accurate Is The Stock Voltage Gauge
i want to know how accurate it is because i would drive around and see it move from 12-14v. it will stay at 12 for about a block or 2 then move up stay, then drop, etc. i would turn off the car it would be able to start again. looked at the alt. looks like it was bought at a junkyard (seen the markings). the car drives fine, so would it be the alt. or the gauge?
thanks
thanks

mine is very accurate actually, i was having some mysterious battery draining problems, i fixed it, but all throughout the problem time my voltage gauge never lied to me, even compared to a mulitmeter.

well it required a lot of wire hunting. i had a short on one of the ground wires connected to the body. i just pulled fuses untill i found what was drawing the current.

My voltage rises and falls depending on the electrical load. If nothing but my radio, it stays above the 12 mark. But once I flip on the headlights, it goes down slightly but still over 12V. But if i have the heater, rear defrost, and headlights, it drops to 12V. But when you are crusing along it stays up but when you are at an idle the voltage drops down an everything dims a touch. Its probably due to poor grounding. I have a new alt. and battery which helped. But its still there, just not as bad.
