'69 Cuda temp gauge not working

You may already know the fuel gauge has voltage regulator inside it that "runs" the rest of . That may be an issue as well.
Yeah, if I can recall now...this was last year, and I’m almost 66, so here goes; I think the fuel was reading too high while out for a drive, and then I noticed the temp gauge pegged to the right. Pulled into a friends driveway and then discovered the melted wires. Peeled them apart, taped them up and drove home. As soon as we separated the melted wires the temp gauge dropped to zero and has been there ever since. The fuel gauge returned to normal, and the oil gauge didn't seem to change at all from normal.
