So I got a 91 RS. I noticed that the temp gauge in the car won't go past 100 degrees. Seems like it's stuck. It will move when the engine is started, but won't show the actual temp of the engine. I replaced the sensor, and nothing. I replaced the thermostat (for another issue I'm having) and nothing.

Now I have the cluster out of the car and I am running a meter to everything I can find. I have it going from the sensor leads to the pins in the dash. I get a reading on the grounds, but I am getting nothing when I try to test the actual sensor wire to the pin. Anyone else have this problem? That seems to be telling me it is a faulty wire somewhere in there, but I am not too sure.
