Hi all. Glad to be here. I have a temp gauge ? about 66 Polara. I removed the gauge pod to replace a burned out bulb and when I put it back in the temp gauge was pegged at H. It took a few tries of shutting the ignition off to get it to go down to C as they normally do but as soon as the key was turned back on it pegs to H. During a 20 minute drive to the gas station it went all the way down to C and been there sense. It worked fine before I took the cluster out. Is it the temp sending unit or the voltage limiter? Thanks.
