Finished right wing riveting!!
Big day today. I started running the EFIS wires around a bit more seriously. I discovered there were two black wires, when I was expecting one. The shorter one didn’t seem to be connected to anything and then I figured out it was the shields for the communication wires. It’s supposed to be connected to a ground. I’m sure there’s a better connector housing out there (i.e. not plastic) that the wire could have been connected to and then it would have been automatically grounded.
I debated quite a bit on how to hook the various wires from the avionics harness to the EFIS harness. In the end, I decided no intermediate connector would be best. I tore apart the EFIS harness a bit, removed the appropriate wires/pins, crimped pins onto the end of the avionics harness wires and integrated them into the EFIS harness. Worked out really well. I attached the EFIS altitude output to the transponder, the serial line to the GPS, and the audio output to the audio panel. There are a couple of extra wires I’m not using right now. Instead of removing them, I put shrink wrap over the ends and coiled them up. The only wire not connected yet is the flap position contact for the AOA.
As long as I was working on wiring, I ran some wires to the F-704 covers for the cabin lights and connected them to the dimmer. I also connected the capacitive fuel sender converters to power and ground. I decided to put them on the avionics bus with the EFIS and EMS. I also ran some wires to the EMS area for power and ground. I guess I’ll be making mine own connector for that, which is just fine.
On top of all that progress, Julie was ready to finish off the right wing bottom skin. Adele had a friend over playing, so what could be more fun than riveting on a Saturday night?!? We got it finished off. Woo hoo! One down, one to go.
