The issue is that there is little or no discrimination on my fuel gauges from empty to full. I have the G3X set for resistance senders, and see little or no voltage difference between voltage levels when the tanks are empty, hold 5, 10, 15, 20, 25 or 30 gallons. I've temporarily wired in a known good S/W sender so I can move the arm up and down while in the cockpit to see what impact moving the float arm has on the voltage drop according to the G3X. Basically nada.
On the other hand, when I use a multimeter to check resistance through the sender itself, the resistance varies by a factor of 10 as I move the arm through its arc.
My request is for someone who's flying a G3X with the S/W senders to take a screenshot or publish the voltage values from the calibration page. I'd like to get a sense of how much voltage drop there is at various fuel levels, so I can recognize reasonable readings when I eventually get them.
P.S. When I spoke with one of the the G3Xperts, he opined that it is a wiring issue. I'm dreading the possibility I have to pull the engine sensor wiring harness. That's a bad job.
