i have a 1986 trans am and i cant get my temp gage to work...i have changed the gage..i put in a new sending unit and nouthing its driving me crazy can any one help? the gage moves all the way ove to the right when i star the car and then sits at 100deg after that

Might be a bad connection at the PC board on the back of the IP. Check to see if you're getting voltage to the sender. If not, you'll just have to chase the circuit back to the guage to see where the open is.
