Re: Temp guage

sender should send you a variable resistance to ground. Assume you changed the sender? Tough call from here not knowing what all you have done in your restoration.

Re: Temp guage

You should also check the sender and check the wire for a short.

Re: Temp guage

I think I will change the printed circuit, I now have no voltage going to the gauge. I had trouble making the fuel gauge work, had to keep moving the connector that plugin the circuit board. The temp gauge has not worked since the PO had it.

Re: Temp guage

I think you're on the right track with the printed circuit. If I remember right, the lands can get loose and break where the connector goes in. I vaguely recall something similar with one of my guages and it was a loose land.
