This is probably just going to be a forehead slap opportunity but maybe someone knows this one. I started doing my fuel level calibration last night - Dynon Skyview HDX, standard resistive type fuel senders connected to default EMS pins (20 and 21). I started with the left tank and was prompted to do repeating 5L pours. I did 3 pours and the sensor reading wasn't changing, Skyview was complaining about that. I decided to abandon my calibration and check the sensor levels on the debug screen, think that maybe I'd reversed left and right. What I found was the left value was ~3.7V and the right value was ~2.9V. The left one was the same value showing on the calibration screen. I decided to try a pour in the right tank to see if the sensor value changed. It didn't. I don't get any movement on either sensor.
I expect that this is an installation error. I recall checking the senders with a multimeter before installing them and they worked fine. Unless I completely missed the point, there is only one wire connecting the screw on the sender to the EMS wire. I'll climb under my panel tonight to confirm the connections but hoped that maybe someone has an idea of what I did wrong?
Thanks for your help.
