temp guage help
Hi there, I'm trying to get the factory temp guage working in my 85 f body.
Car is carb'd, and had a set of 920 heads on it. The temp probe was installed in the drivers side head and worked no problem. When i switched heads to alum the hole for the sender is smaller, its actually a factory size as opposed to the larger sender that was in there and working fine. I ordered a new factory sender, installed and hooked up the wire. Now it wont read. I then replace the wire as far up in the harness as i could go thinking maybe I pinched it when I had the motor apart, still no dice. I thought maybe it was not grounding well through the head, so I ran a wire from the threads on the sender to a ground, and all that did was make the guage go full pin. I'm lost here, and really don't wanna go after market if I can avoid it. Any suggestions?
