Took my 9A up to do to work on some of the test flight time.
I was flying along working on getting comfortable with the AP, when the entire electrical system went dead.
Just as I was starting to try and figure out what the problem was, everything started rebooting.
After the screens came back up, the VPX gave me an overvoltage error and said it had shut down the Alternator field.
I talked with Chad, and he confirmed that the VPX behaved as designed in an overvoltage situation. It should shut down, and then come back up with the alternator field disabled, so that is good.
Here are my questions:
1 - I have less than nine hours on the plane. How likely is it that the alternator really did go bad? It is a plane power. I took it to the local auto parts store, and they tried to run a test on it, but couldn't figure out how to hook up the alt field lead. However, he did run the voltage test and it failed. I'll call plane power in the morning, but how reliable is that test without the alt field enabled?
2 - I have an IBBS backup battery that has the main screen, engine monitor and one ADAHRS wired directly to it. Why would they all reboot as well? This one really concerns me since I hope to use this as an IFR airplane eventually.
Thanks!
