Re: 1971 GMC temp gauge
Quote:
Turn the key on and see if gauge goes back to normal cold position with it disconnected. If it does, it's probably the sending unit gone bad. The sending unit is like a door to ground for the gauge. As the temp goes up it opens up more. If it's open all the way, the gauge is pegged on hot.
