Flying again!
Well Known Member
My RV-10 has been flying since 2005. Standard Vans flaot sender.
I removed the tanks to have them sealed by Weep No More. I installed them and put 10 gallons in the both tanks. The left tank was showing 7 gallons with 10 in them. I checked to make sure the "AuxSF" and AuxOff" had not changed in the setting. I then changed the Aux SF by 5 to see what change that would make to the displayed fuel level. The fuel level changed to 131 gallons! I changed back to the previous setting and the fuel level was 112.
I drained the fuel and went through the calibration steps. I also measured the resistance of the sender empty (248 ohms) and full (52 ohms at 23 gallons when the sender tops out). The sender seems to be operating correctly. I did the math and came up with AuxSF and AuxOff that were the same as the last time I calibrated 5 years ago.
I plugged in the new values and now it shows 91 gallons!
I am stumped - anyone have any ideas?
I am finally cleared to fly again and now I can't get the fuel leve to display correctly - very frustrating.
Thanks in advance for any ideas -- TJ
