this dont help you. but there is no difference in left and right heads they are the same thats why you have outlets on both sides just fyi. i tried to reread it but, does it still go at 3 o'clock with the key off?

Correct. The behavior is exactly the same. I might be making a run to the junkyard tomorrow and will see if I can get a gauge. Is there any way to know I'm getting a good one? I'll stay away from any pointing to 3 o'clock of course. LOL

it would take some rigging to get something to work like that there was a write up about how to test a fuel gauge with the headlight switch but idk about the temp should be about the same ideal. i would take zieg up on his offer. That way you cant really go wrong

My temp gauge does that as well. Sometimes it will even spin clockwise out of control then stop and go counter clockwise. But it is a work in progress.

I got another gauge from the junkyard. It still registers too hot, but it's at least on the scale now. I verified with my infrared thermometer that it's not running hot, so I'll take this gauge back and try another.
