Finished enough of the AOA wiring to power it up and see if it works. I still have to hook up the annunciator, flap switch and audio. I uploaded the latest firmware into the Dynon EFIS-D10. It worked flawlessly. I played around with the checklists a little bit. I still have some configuration to do to get it perfect but I think I'll be really happy with this box. I started wiring up the GRT EIS-4000 Engine monitor. I managed to get all of the EGT / CHT's wired as well as power and the manifold pressure sensor.
Mounted the fuel pressure and oil pressure senders. Pulled the wires through the firewall for these senders and hooked up all but the grounds. I also hooked up the P-lead wires and pulled them through the firewall.
Hooked the P-lead up to the switch in the cockpit. Wired the tach input to this same switch. I also put the OAT sensor for the EIS into the NACA duct on the passenger side and wired it up.
Finished all the wiring on the EIS engine monitor (except the annunciator output) and powered it up. It showed a few temperatures that seemed about right but without any calibrations I really couldn't test much. It does work though. I hooked the power up to the MP3/CD player and I also installed my cargo lights, which are nothing more than those cold cathode tubes that people put inside glass cased computers to fancy them up. I mounted them under the seat-back bulkhead.
Built a bracket under the co-pilot seat for the two relays that I will use for the flaps.
I thought that I could get the flap wiring finished up tonight but it turned out to be a bigger job than I thought.
Finally finished the flap wiring, and actually moved the flaps. It's fun to see stuff move.
Finished wiring the Landing / Taxi lights. I also wired up the postition lights. I rigged up a way to test the Wig Wag flashre on the L/T lights and I don't think that I am going to be happy with it. I will probably redo it.
Finished the last of the Lightspeed Electronic Ignition wiring by hooking the coax up to the coils. I then started scratching my head about where to put the headset jacks.
I think I may use a couple of little platic boxes from Radio Shack to put my headset jacks in. This will give the cables some support and eliminate the need to have the little isolation washers. I plan to mount them to the bottom of the sub panel.
I drilled the holes in the sub panel for my little headset jack boxes and I finished soldering the wires to the DRE intercom connector.
Still soldering on the intercom wiring. I managed to get the relay done that I put in for switching com 1 to com 2. (I don't have a com 2 but I think I may expand so I put the relay in just in case.) It is a passive mixing circuit that I got from Garth at DRE. I also started soldering the wires to the headset jacks. When I screwed one up I decided that I had breathed enough lead vapor.
Finished soldering the headset jacks in the little boxes and put the intercom wiring harness into the panel. I started hooking up power running the wires around to where they need to be.
Finished mounting the headset jack boxes under the panel, connected the CD/MP3 player to the intercom and hooked up the PTT wiring to the pilot side stick grip (co-pilot grip is in the mail). I plugged my headset in and gave them to Shannon to put on, then turned on the MP3 player. When her head started bobbing I knew it was working. Once all that was working well I hooked up the audio output of the AOA to the passive mixer circuit and it worked.
Hooked up the flap switch to the AOA and that completes the AOA wiring. I made a plate for the comm antenna mount and Daryl came by and helped me rivet it to the plane. He also brought another headset so we could test out the intercom some more (I only have one headset). That DRE-244e works as advertised. If it works that well with all the airplane noise I'll be thrilled with it. Once I got the antenna mounted I finished all the rest of the wiring to the ICOM A-200 com radio and turned it on. Nothing :-(. Look at the drawings again, and see the text "jumpers MUST be installed" DOH!! Okay install the jumpers and try again. WHOO HOOO!! I dialed in the CTAF for West Houston and actually heard somebody in the pattern. I pushed the PTT and the TX light came on. It's all very exciting.
Tonight I worked on the Electronics International Dual Fuel Level guage. I got the power and the backlight hooked up but I am still debating on where to punch a hole in the side of the airplane for the probe wires to pass through. They can't go through the other holes because the fuel probes are forward of the spar and I ain't drillin' no holes in the spar to pass wires through.
