Just got the car out from winter storage and I am having problems with the temperature gauge and the voltameter. I know the alternator is working and charging. Anything else you guys can help me out with?

Mitch , where do you store your car ? Is it possible that some critters ( mice , squirrels , etc. ) had access and may have chewed on and damaged wiring under the hood ? Look under the hood for any obvious signs of this .

Have looked quite a bit for any wires that were chewed on, it is not very possible but may have happened. The thing is these are in 2 different wiring harnesses going to the engine bay so also not likely something chewed on both and everything else works fine haha.
