68 SS w/ Gauges

699 Views 8 Replies 4 Participants Last post by  swilk
I just bought a 68 SS with factory gauges ... and cant get the temp gauge to work. I have installed a new sending unit with no luck. Whenever you starte the car, the gauge does go to the coldest position ... but it just stays there. What is the path of the circuit? How often do these gauges go bad ... and is a replacement available? Thanks for any help you can give.

Before you send the gage out for repair, there is a possibility that the calibration resistor is bad. It’s that white ceramic block on the backside. The gage doesn’t quite act like a bad resistor but worth a shot. Find something like a late 70s pick-up truck with a temp gage and take one off of it. They are all pretty much the same.
There are places that repair gages but I don’t have a link with me right now.
