trouble shooting a fuel gauge
I installed a Autometer(0 to 90 ohm) sending unit in my poly gas tank. I ran 2 wires(one from the sending unit terminal & one from the sending unit ground) to the gauge. There is also a hot wire from ign to gauge.
The gauge reads below empty....if I put second wire from the sending unit ground to frame It reads above full.
The resistance between the 2 sending unit terminals reads 60 ohms.
What now.....Bad gauge? everything is new.
