oldred98 Posted October 2, 2007 Report Share Posted October 2, 2007 ok, i put the digital dash in my 92 c/s a few monthys back, but did not as yet change the water or oil sending units. Yesterday, the water temp gauge is pegged, but the water temp is only 150 degrees. I unplugged the wire to the sensor, and same result. Is the (idiot light)sending unit a normally closed switch? The temp gauge switch is a rheostat, always closed, so why do I still get a hot engine indication? any thoughts? Quote Link to comment Share on other sites More sharing options...
