Just installed an autometer electric water temp gauge...it's just a 3 wire hookup, 1 to ground, 1 to the sender, and one to an ignition source. I have a good ground, it's wired to the sender (which is installed in the upper radiator hose), and I hooked up the ignition source to the cigarette lighter. The needle moves, but doesn't go past 100 deg. F., so it just barely moves when I turn the key then stays there the rest of the day.
I'm thinking my ignition wire is off. Where should I wire it to then? I just thought any constant 12v source would work, guess not though. Where is everybody elses wired to? Thanks alot.
Hooking up water temp gauge?

it sounds like either the sender is messed or there is a bad connection. The cigarette lighter should be fine for power supply. Recheck all your wiring.

Re: Hooking up water temp gauge? (SideWays=smiles)
All of the wiring is just fine. I moved the ignition source to a different 12v source and it didn't change anything. The wiring is perfectly fine though....I'm guessing the sender is a dude then? Don't know how the hell that happened, it's a brand new gauge. Any way to test the sender to see if it's bad?

Well, I just heard that your supposed to ground out the water temp adapter...I didn't have a clue. Duh, that's probably what the other screw is in there for. Can anybody confirm this?

Re: (White Comet)
Yeah, I was talking to autometer customer service. They said that all inline hose water temp adapters should have an extra bolt/threaded hole to ground it out. Mine did at least, and that fixed my problem pronto. Works great now!
Re: (onecrazyfoo4u)
ahh so thats why my adapter has an extra bolt on it that seemed to do nothing. good looking out, i have to wire that crap up soon too.
