Chapter 22 – More Electrons

Or maybe rather I should say: “More Paper!”

I spoke at length with Bob from TCW Technologies twice today to finalize my Integrated Backup Battery System (IBBS) circuit configuration.  While reviewing the installation manual I ran into some questions on the Pass Thru pins on the IBBS.  Changing over to the X-Bus configuration and adding a switch apparently jumbled up my circuitry a bit and Bob was nice enough to walk me through how to get back on the straight and narrow path.

In short, at a minimum I eliminated another switch off the panel and it looks promising that I’ll be replacing the 8-port ATC fuse panel that is the X-Bus, for a 9-pin D-Sub connector, thus saving weight and of course space on the Triparagon.  With a total rework of the IBBS wiring, I wanted to get my notes transferred over into reality on the IBBS/X-Bus wiring diagram.  In addition, as I worked to organize & update the wiring schemes in my electrical system I finally had enough of tracking a bunch of info on a clipboard, so I ended up creating 2 new diagrams that I’ve long since had on my diagram list:

18. AG6 Annunciators
27. Main Power Buss

Yes, I’m guilty of getting a bit sidetracked since I do have an entire task list of stuff to do down in the shop to finish off the Triparagon build & install to get to  . . . yep, wait for it . . .


Ok, my focus failings aside, here’s the latest updated list showing the Electrical System Wiring Diagram status:
