Temp Gauge Problem

I just reinstalled my dash on my 68 SS. The temp gauge which worked correctly before disassembly now shows cold when the engine is running and when I turn the engine off it registers normal temperature. As soon as I switch the key back on the gauge goes immediately back to full cold. Sounds like a grounding issue but I'm lost on what to do. Any suggestions would be greatly appreciated. Thanks.

Re: Temp Gauge Problem

Have you tried grounding the under hood sender wire to bare engine metal to see if the gauge pegs hot with the key "on"?

Are there any other dash issues? (I.e. gas gauge pegs when headlights are on, turnsignal indicators mysteriously glow etc?)

Re: Temp Gauge Problem

Thanks for the suggestion, Coppertop. I looked at the sending unit on the engine and the wire was very, very loose. The connector is shot. Works as advertised when held on by hand. I'll get a new connector and the problem is solved. I must of had the problem before dash removal and just didn't notice. I feel kind of silly not checking before posting on the forum. Another lesson learned.
