Temp gauge reads with lights on
 

My temp gauges pins when I turn on head lights (no key in ignition) when I start the car it seems to read normal but not really sure if it’s correct, has this happened to anyone else not sure if it’s the gauge, ignition switch, or a dreaded short some where, and if I take the wire off the sender it still pins when I just put the lights on
92 lx was a 2.3 now a 302

Mine jumps about 1/4 of a peg when the lights are on. I really want to keep the interior looking stock, but I've already lost my tach and the fuel gauge refuses to top off. I agree that the stock gauges suck after years of use.

temp gauge is fine under all condition except when lights on key off

My fuel will not go to the top and the temp jumps about a needles width, with the lights on also. When I got my car, the oil gauge was very low. I put a manual gauge on it and the oil presure was great. I removed the cluster and took it apart and put the white gauge backing and a 140 speedo, reset all the gauges and they work great. I am still going to go with manual gauges in the near future. Just dont trust the factory ones and read to much bad about them on here.
