Chapter 22 – X-Bus wired up

This blog post covers the past 2 days.

Well, as has been the usual modus operandi for the wiring up of this bird, the X-Bus took significantly more time than I expected.  Mainly due to the fact that I added in the 4-position fuse panel into the mix to ensure a number of my critical panel components (including every EFIS) power inputs were fused.

The addition of this fuse panel meant depinning a number of component power wires from the X-Bus D-Sub connector and then splicing wires to lengthen them for their new journey to the X-Bus fuse panel.

But it all turned out well in the end, and here we have the X-Bus fuse panel with power from the X-Bus D-Sub connector, and with all the fused component wires terminated to it.  I’ll note that I’ll finish wrangling the wires to make them look tidy after I install the autopilot pitch servo and run the wires (white cable in left/center of pic) to it in this bundle of X-Bus wires.

I will also note that the vast majority of the wiring is done, with a few holdout pockets that need to be undertaken as a task of their own: mainly the video camera wiring and the intercom wiring.  And some mop-up tasks on a few things like the indicator lights, just to finish those connections.  With that being said, I seriously see the wiring getting exponentially less over the next week as I transition into installing the panel displays and instruments.

For example, here we have the E-Bus fuse panel, with all component wires terminated except for one: the ELT (ok, maybe add that to a separate wiring sub-task… ha!).  The Master Bus panel is pretty much the same, with only a couple of terminations remaining.  I’ll say the same thing for the ground busses, with only a handful of terminations left on those as well.

For those of you that know…. you know, but I’ll be taking the next couple days off.

But when I return, I’ll get back to the big push!
