I haven't flown much for the last two years (fixing that problem... did BFR last week and scheduled a CFII so I'll be flying weekly working on that)

BUT, when I shut off the avionics master my D-100 goes black. I assume it's the battery.

Is there anything I can do diagnostically before buying a replacement?

While I'm at it, what is the current SW release for the D-100. Full system is D-100, AP-74, HS-34, two servos, magnetometer and OAT probe.

Thank you!
