Temperature Guage won't go off cold
« on: September 26, 2017, 07:35:24 PM »
Restored my car with a new engine wiring harness. All guages worked before disassembly.  After re-assembly, the original temp guage doesn't work. Stays on cold. Goes hot when grounded.  Have changed out the temperature sender twice with no teflon tape. Just bought a repro fuel guage for the car and it doesn't work. Any suggestions as to what is wrong ?

Sounds like you're missing a ground somewhere. Sometimes too much paint in the wrong place will cause that problem....Joe

All the other guages work though so I didn't think it would be a ground

I had the same issue, new wiring, I had the leads reversed on the back of the gauge,I changed them around, works great now.....I used American Auto Wire for my new wiring harness!
