I went to the hangar today and finished up what I could of the stack wiring. Apart from the ACU, it’s complete. All the wires running to the back of the stack are now complete. All that I need to do now are connect them to the ACU, and then the ACU to the EFIS 1. Then, I think it’s pretty much done. I still have some other wires to run for some of the lighting switches, and I need to do the antenna cables for the stack. I also need to connect all the ground wires for the stack, but I’m going to leave them until the last minute in case I need to add something else. I also added wiring for a music input. Maybe a satellite radio will be in the works one day!

For the xpdr issue, I checked the output voltages for the grey code, and all measured 3.32v or 0v. So, 3.5v is what’s needed, and 3.32v doesn’t cut it. I’ll call BMA tomorrow and get them to send me an amplifier card. Then we should be good. See my EFIS page for details on this issue.
