Hi folks, I'm having issues calibrating my fuel tanks with float sensors and a G3X touch. I've determined that the resistance option (as opposed to voltage) is the correct option, but when I generate the calibration curve, the difference between empty and full is only about 34 millivolts. Garmin says it should be volts. When I save and re-boot the G3X, it shows my tanks are empty. My understanding of the Stewart Warner senders is that empty should give 240 ohms, and full around 30 ohms. I'm going to drain the tanks and check that I'm seeing those numbers (I think I can push them up thru the tank drain hole).
Anything else I should check?
