Hey bartamos. thanks for answering.
Gauge part # GTS4743 from Brothers. Original style sending unit. Yes 30 OHM.
No gauge is not wired backward, I'm sure.
Sender wire itself is not grounded. Ground is at sending unit, and metal housing (gauge case) where fuel gauge (and other gauges) are attached.
Sending unit grounded near negative battery terminal on frame.
Ok I have the 12v at the gauge terminal connected. I removed sending unit wire (at the sending unit) that goes to the gauge. Yes it reads max full.
Connected the sending terminal to ground (I used the ground wire from the sending unit). Nothing happened.
What do you think?
