Misc Avionics Stuff

I opened the new SkyView Display Harness and installed the panel mount USB cable.

While looking at the wiring diagram for the transponder, I noticed that there were a couple of loopbacks, so I installed these using some 22AWG wire.

I also got an order from Van’s that included this pressure switch.  I installed it in the right port of the manifold using an AN915-1 elbow.  This will drive both the hobbs meter (connected to the NO pin) as well as one of the annunciator lights to indicate low oil pressure.

I went ahead and installed a wire to the ground pin.  Since I don’t have a ground block on the firewall side, I ran this through the pass through so I can connect it to the ground block on the cabin side.

I decided to go ahead and label the ground wires.  The labels are facing downward since I’ll only be able to see this from below once the last skin goes on.

I have no idea why I didn’t think of this before.  Since I have a label maker that will print on heat shrink tubing, I printed up some labels for my drill bits.  Trying to read these numbers on the bits themselves has become quite a pain.  You can also see that I put the screw/bolt size on the label as well so I don’t have to look these up on a drill guide.

I installed the ARINC-429 module on the front side of the subpanel on the pilot’s side.

I installed the backup battery for the left display on the back side of the subpanel.  Batteries have to be replaced from time to time, so I wanted these to be fairly easy to access.  With the tipup canopy open, these are easily accessible.

I also put a new terminal on the battery positive cable with a 12AWG wire for the battery bus.

I also installed a couple of adel clamps to tie the battery positive cable to the engine mount.  Without this, the terminals would have to carry all of the weight of this cable (and it can weight quite a bit when I’m pulling 6Gs).

The battery bus cable comes through the pass-through and will connect to the battery bus via the bolt on the bottom.
