: 1970 Deville with gauges problem

My temperature light went on in my car. I checked the entire cooland system including replacing the thermostat just in case. The light still turns on but it turns off on turns and it stays on after the car is off. I am starting to believe that the gauge has a short. How do I go about doing the diagnostics to figure out where the problem is.

Thanks everyone,

Fernando

The wire to the sender is shorting to ground, probably is disconnected and touching metal when you turn a corner. coolant temp sender is usually in the intake manifold somewhere.
