Project repair completed!!!
Thanks fellow Beaver Ron Rowe for the extra hands! The repair really is a 2 man project dropping the ceiling panel. Once we got it down, the failure was the same type that Ron had on his rear lighting panel. The connection point for some reason shorts, and you can see the resulting burn out once the panel is down.
I did the same repair that Ron had done on his, cut the supply wire and cut the lighting rope, then rejoin the 2 sections without the factory coupling. We just striped to bear the wires and used wire nuts and tape, job done.
The hard part was getting the panel back in place, but with the extra hands (thanks fellow pilot Ron) it was a
simple matter, and then we had time to enjoy a BEER and do a little hangar flying.
