Fuel "Control monitor" or "Signal conditioner"

That is rather annoying, as these people have had the box twice or is it three times and found faults that during the first test should have been cleared. You know it is much like the UK now to get a unit repaired like yours is almost impossible, to get a radio repaired in the UK is the same. The skilled people are just not here any more.
The Skymaster is a easy airplane to both service and troubleshoot all you have to do is go back a few years and think logically.
