1. Fabricated an 8-foot intermediate harness to connect each wing with its respective fuselage connector.
2. Tested both wing nav lights and strobe lights. Everything works.
3. Tested landing lights. The right one works, but the left one does not. Began troubleshooting by hooking the right wing fuselage connector to the left wing. The left landing light still does not work, so the problem is somewhere in the left wing. Looks like I will have to cut into my nice neat wing harness to see if power is getting out to the wingtip.
4. Programmed the landing light wig-wag module for "single switch" operation. This will turn on both lights "steady" upon activating the switch the first time, and will make it easier to diagnose any wiring issues.
5. Loaded my free North America GTN nav database into the unit. Played around with it and the GDU to see how they interact. I doesn't appear they are sharing much nav data yet.
6. Practiced loading flight plans, changing chart types, activating instrument approaches, setting minimums, tuning navaids, sequencing waypoints, and more, on the GDU. This thing is so impressive.
