Just got an interesting phone call from Aero-Mach Labs. They told me after receiving my original signal conditioner back at their shop for the third time (after I decided to keep the "overhauled" unit), they bench tested it again and found 5 more failed transistors. This really makes me wonder if the "overhauled" unit I now have is any better than the original one. They did say that under warranty for one year they would be happy to give my overhauled unit that I now have a free "check-up" to see how it is doing. I think I will do that in August/September 2009 when the airplane goes in for annual.

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. Regards Pete

I just wanted to give an update on my fuel guages. I have been flying with the "overhauled" signal conditioner about 6 months now (about 50 hours) and everything seems to be in good working order. When we first installed the replacement signal conditioner, I would occasionally see both fuel guages drop off line for a few seconds and then come back to life. I have not observed that behavior of the guages in probably the last 25 hours or so. They seem to be steady, and accurate. We shall see how long it lasts but for now, all is well.

[quote=edasmus;13898]Just got an interesting phone call from Aero-Mach
Anyone have a schematic for the fuel monitor box? That would be helpful. Aero Mach repaired mine but it still didn't work - mechanic here too busy so I did some troubleshooting and found the shielded cable to the outer probe was shorted. After replacing the box would work after warming up for 15 minutes. Just a month out of warranty Aero Mach wants another 800 to repair again. I'd like to trouble shoot the unit myself but need a schematic. Greatly appreciate any help and happy to pay for copy.
