i have two indiglo auto meter gauges one oil pres and the other water temp. heres the porblem the water temp is not working, every time i turn the key from the off position the needle just flings right across to the other side. does this mean that the gauge is broken? or could this be caused from a bad ground?what would make it do this?

 

Most likely the wire going to the sender is shorted to ground, or the sender is shorted. Check the wiring to make you sure you don't have your sender and ground wires mixed up.

 

hum.... i dont think i could have mixed up the two wires but i will double check to make sure.
also i will make sure is has a good ground. what do u mean by short in the wire? what does short in the wire mean?? >like its connection is not good/wire is on loose..not getting a good connection?
thanks4 helpin me.

 

Shorted as in connected directly to ground, intentional or not. May be caused by a pinched wire.
