Nice that you had a backup autopilot to fly while you troubleshot the problem 😊. What alternator do you have? Also, I’m surprised you got VPX faults on individual circuits for an alternator failure rather than a warning that the alternator had failed. Thanks for posting this. I have a VPX in my RV-8 (but no backup alternator) so it’s good to see how an Alt failure might look.
The original was a Plane Power AL12-EE70/B with a R1224 External Regulator. After troubleshooting I replaced the R1224 as I couldn't get myself to believe it was the alternator. Short story, it was the alternator. I replaced it with a certified AL12-70. (mainly because that is what I could get next day).
Did you figure out what happened to pri alt? What kind was it? Do you think it’s better to run both pri and stby simultaneously with stby volts set lower or to manually switch pri to stby. It seemed like your pri voltage stable but current up and down. Did ANL fuse blow?
I only ever have one alternator active at any given time. When I took apart the alternator it looks like the slip ring had a build up on it that ended up sorting out the shaft to ground. Not sure how that happened but in short the field 1 wire was shorted and no longer working.
I have my voltages set separately between the two alternators not because I run them both simultaneously but rather so I know what I’m looking at when I change which alternator is active. Also, with the change of one wire I could have two completely separate busses run from two different alternators, but in the current configuration I have a cross feed between the two busses controlled by a switch.

Never keep just resetting over current on the VPX or breakers. They trip for a reason!
Glad everything worked out.
Nice. Gotta love the redundancy
You don’t need it until you need it. Would have been a long drive home without it.
I love this video!

What avionics etc are you running in that RV10?

I thought RV 10's had 4 seats?
It does. Camera fish eye gives a weird perspective.
