The fuel level sensors on one of my GRT EIS systems is giving me fits.
Using resistance type fuel level sensors and have the resistors installed per instructions.
The system has been calibrated and is working normal most of the time.
Occasionally on power up I will notice that the displayed fuel level is less than it was at shut down by 3-7 gal or so each side. By powering down the EIS and restarting, the system will display the correct quantity.
There is no indication that there is a problem other than by me noticing the level is not correct or by manual cross checking the level with the fuel totalizer.
I have been taught in flying to "never trust the fuel gauge" but I still don't like equipment that in not working correctly.
I called GRT and the only advice I could get from them is you must have a loose wire on the fuel gauge. Checked and found nothing. Also unlikely as both tanks do the same thing simultaneously.
Anyone run into this?
