I think I have a gremlin in my wiring harness.
In doing my current rebuild of my '79 CJ7 , I replaced all the gauges with Stewart Warner Wings gauges. I have all of them working, except the fuel gauge which is causing me fits. It is a 90-0 ohm gauge, which I know is different than the OEM sending unit so it will never read accurately, However it is reading backwards: Full when empty and empty when full. I have messed with all the wires, re ground everything, and still cannot figure this one out.
Of note, I installed a Painless Wiring universal CJ harness, and am wondering if that is the culprit, as I have found several errors in their wiring diagrams.
Thanks,
jim
