My coolant temp gauge died last summer. It immediately drops all the way past normal and sits there. I've tried changing the sender and gauge to no effect. I tested the gauge by applying 12V and it does a complete sweep. I tried testing the sender by checking resistance with a meter, but I couldn't get any readings that made sense.
I know there is power because the gauge moves when the needle is manually moved up and then power is applied to the vehicle. Any ideas on what to do next?
