Question about 1987 Ford Mustang
Hi Randy, If there is no movement when shorting the electrical cable to the body, it seems there is an open circuit between the gauge and sender unit. The problem is wiring. Regards John

Hi. the vdc at the sensor seems to be fine. if the ground is sufficient, i would replace the gauge. its malfunctioning. Check for loose connection at gauge before replacing the gauge.

YOur guage is faulty. Your will need to replace your guage if it stays in the hot position even when your car is off and your key is out of the ignition. If it only rises to hot when you turn the key to the run position, you have a wire between your guage and your temp sending unit that has been gounded out. Usually this happens when a person opens their hood to add oil or perform some minor maintenance on the engine and inadvertantly bumps the sensor or switch or wiring. This causes about 65% of these minor issues people incur, but if it does stay all the way up with your key out of the ignition switch, then you will need to replace your temp guage.
