Default Re: Temperature gauge always hot?

The description you give of your gauge's behavior suggests that the polarity is incorrect. The 55 was originally +ve earth and I presume you now have it wired -ve earth. I know it has been mentioned that polarity does not matter with these gauges but I would give it a try. Swap the connections on the temp gauge and see if it makes a difference.
It seems like you have done everything else right, so what have you got to lose.
If it still behaves the same you know once you make sure that you have the correct sender, it can only be that the gauge us faulty.
Macs sell new gauges but they aren't cheap.
Regards
