Question
JoeH
Gauge worked fine up until the other day when I replaced the sending unit gasket. Now the gauge is pegged down to about a 5 o'clock position...
I read 4.3 volts from positive to negative wires on the sending unit, and 4.3 volts to a known good ground. I did reroute the sending unit wires as I didn't like them laying loosely on the top of the transmission. Damaged wire strands? It had been folded back and forth about 5 times and zip tied to the fuel tank lines. I straightened it out so I could run it along the crossmember.
