Hopefully, this will be the last question and the next post by me will be an update as to the success thanks to everyone's help. I have fixed the wires on my instrument cluster with good results. Now the gas gauge is functioning correctly. The temperature gauge is still not working correctly. It starts to rise (very little) and then abruptly snaps back down and repeats this never even getting into the actual temperature area. I'm guessing now that it is most likely the gauge itself. Could I have fried it when I put the 1973 voltage stabilizer in because it works on a higher level? Or maybe it just went bad and needs to be replaced. Will a gauge from a 1973 work if it was made for a different voltage stabilizer? Thanks so much for helping me work through this.
