Ok, I have an autometer Electric water temp. gauge and I am having a hard time with it working right. I have the sender tapped into the thermostat housing piece and it is reading 250*. when the engine is cold it starts low and climbs all the way up. I have no idea what the problem is. Can anyone give me an idea or a link on how to hook it up. I'm sure I hooked it up right but..... it wont work. please help.
