Prior to powering up the avionics, I found the backup battery power connector broken. Since this is a used unit, it was going to cost $250 flat rate plus r/t shipping. Ouch!
Friends to the rescue. Spent about 2 hours today having it worked on. Now have a completely functional backup battery for the D10A. Cost- two cokes and some future beer.
Came home and routed tail beacon wire and worked on fitting left rear window for about 30 minutes. I think it is good to go.
