Debugged and resolve mic problem. Tip and ring wires were swapped. This was the way the harness was built. I think I would have made the same mistake.
Continue testing SL40 and 240. Everything working properly.
Final install of headset jacks, including enlarging holes in side panels for proper fit of jack isolation washers.
Continue securing wiring. The front is coming together. I see how I would do it differently, but this will work and be reliable.
Secure wiring for GPS antennas and temp install of 430 GPS antenna. Will have to redo the 430 puck to provide better weather proofing.
Make and install Nav coax and Glide slope Coax. Getting ready to install and test the 430.
Make inserts for proper installation of aft 12V power jacks. Wayne and I figured out how those "cigarette lighter" jacks are supposed to work. Basically just made two small squares of .032 with 3/4" holes. The outside of the power jack threads off the inside, and the inside just fits the 3/4" hole. When used properly, they fit very nicely. Happy to have that issue resolved. Do final install and labeling of aft power jacks.
