My questions is the water temp sending unit. I installed a 1/8 npt sending unit. I got it from advanced auto. It is a borg and warner. I am not getting a reading. I installed all new wiring in the dash and engine compartment. Gauge was fine from the start. I thought it was my wiring. I pulled plug off sending unit. I grounded the plug to the frame. Turned key, and my gauge went to full "H" for hot. To me the wiring and the gauge is working fine. Do I have the right temp sending unit. I took it back to adavanced auto, thinking it might be a defective sending unit. Installed new one, and it is doing the same. I am stumped. Anybody got any ideas. I got a 66 mustang with the alum head..
I talked to Mike, and he is working on it. He said there might be different amps on the sending units output.
However I did disconnect the pink wire and installed the DUI input wire to ignition switch. I do not think that has anything to do with temp sending unit...
Any comments will be great...
