All-
Looking for some input / wisdom in troubleshooting an electrical issue.
This is the RV-10 that I bought flying, and I don't know the electrical system as well as I would had I built it. Unfortunately, there is no schematic.
I have a new Plane Power alternator (we installed it during the prebuy ~50 hours ago), and a new Odyssey PC925 battery.
Yesterday enroute from KUMP -KOZS (Camdenton, MO) we experienced a total electrical failure about 20 minutes out from OZS. Everything went offline except the 2 EFIS screens (internal batteries). Over the next 5 minutes or so, power came on and off intermittently. I turned off everything but one EFIS screen, the SL30, and the transponder (as I was squawking and using VFR flight following).
The initial shutdown (as best I can recall) happened when I hit the push to talk to transmit.
The master and alt field switches are circuit breaker switches. No breakers popped. Cycling the switches made no difference.
After I shed loads at some point the power stayed on. Volts were at 12.6 and the "ALT" warning light on the panel was illuminated.
I was able to make the approach and landing uneventfully; flaps and fuel boost pump worked fine without any additional power glitches.
I'd appreciate any thoughts / advice on troubleshooting.
My plan today is to go out and check all the wiring that I can access, make sure nothing is loose, etc. I dumped the data from the EFIS (AFS3500) yesterday but forgot to grab it, so I am going to download that and see if there is anything enlightening there.
Thanks in advance.
