RDAC and Emergency Batt switch

3 hours.

Just got back from a 2-week work trip, so I needed a little downtime.   Today I got back into it and wired in the EFIS backup battery switch.  This was wired before, but it was crap, so I redid it.   I also wired the RDAC ground to the engine block, like it says to in the manual.   Apparently wiring it to the secured supply on the EFIS is not correct.   I also got started on wiring the music input.   Took me a second (and the brave sacrifice of a 1/8″ splitter) to figure out which was Tip/Ring/Sleeve, but all that remains there is to drill a hole in the panel, solder the wires on, and snap it in.
