I have a very disconcerting fuel gauge reading problem.
I have an AFS3400 connected to Dynon capacitive senders at the tanks. Every few minutes in flight a tank will, on the gauge drain to zero, then some minutes later refill. It can be either gauge, rarely both together. This generates many disconcerting warnings.
Clearly an intermittent connection is the obvious thing to look for, and I have done this many times. Just occasionally the tank will only partially refill to the actual level for a limited period, but usually it reads correctly or nothing.
Is this problem familiar to anyone else? I begin to wonder if the problem is NOT my external wiring, but either inside the tanks, the Dynon senders or the AFS.
Thoughts?
