FuzzFace2 Posted April 30, 2022 Share Posted April 30, 2022 Oh, bonus... Check to see if the temp gauge spikes with the sender unplugged. If it does, the wire must be shorted to ground somewhere. Maybe the wire got pinched or chafed in the engine bay? Yes this is the way to test if the wire is shorted or not. Gary had you shorting the wire to ground and this would also peg the needle to hot if the key was left on for a little bit. I have never seen the oil / fuel / temp gauge go from 0 to full when turning on the key even with the wires shorted to ground, they move up about the same speed they do down when the key is turned off. I wonder if the printed board is bad to send full volts to the temp gauge? I dont think I would worry about the part numbers when getting a new printed board, just get it for the cluster type. lights / gauges / gauges w/tach.
