Another day full of research, reading, assessment and multiple pitot/static plumbing system reorganizing based on paper design vs the physical space in the bird. I picked up a length of high-end 1/4″ fuel hose to use in the nose to connect the pitot tube to the sidewall pitot tubing… initial tests were good as it didn’t collapse, but still more fine-tuning required.
And although not pictured, I installed “T” fittings on the GRT AHRS box and swapped out a straight fitting on the TruTrak ADI pitot port for a 90° right angle fitting.
I then got busy cutting, trimming and crimping the terminal connectors onto the battery cables. Sorry, no intermittent step pics on those since I was in get ‘er done mode since this whole process is taking way longer than I planned for.
All told the ground cable (right side of battery) that is only visible through its attaching bolt, the left side positive cable on the front side of the battery and the Tri-Paragon ground cable (top battery, right side) were all completed (note the blue fuel-line tubing being tested/configured for the pitot tube).
I still need to terminate the G0 ground bus’s respective nose component ground wires… and clearly for a visual I threw in the Tool Box for a good look at how this area will appear during normal ops; just a bit more tidy. Note the left-side (upper right side of pic) located TCW Technologies Integrated Backup Battery System (IBBS), which will be the subject of my panel components test below.
With the battery in place and cables firmly attached (I will need a more specific bolt, washers, etc. that I plan to acquire tomorrow), I then tested the IBBS back-up battery function by flipping on the IBBS switch (located lower center strut, pic below). This switch flip should have resulted in the GRT Mini-X EFIS, the TruTrak ADI, and the MiniUni2 mini backup EFIS all powering up… as you can see, unfortunately, the ADI did not power up.
But the Mini-X did nicely…
As did the MiniUni2.
Again, here, these are powered via the TCW Tech IBBS (in the nose), NOT the Master Switch (yellow pointer) which remained off during these power-up tests.
As a reminder, the IBBS power switch is the bottom right switch on the center strut of the panel. I forgot to grab a pic, so I reused this one.
Clearly I had an issue with the TruTrak ADI not powering up, but after a good 30 minutes of troubleshooting I fount the culprit: the ADI power wire FastOn at the X-Bus fuse panel. After a lopped off the bad FastOn and crimped a new one on, Viola… issue fixed.
Which resulted in my initial test goal: all 3 panel units powered up via the IBBS powered X-Bus.
Today’s mission complete!
Tomorrow I’ll add the GRT Engine Information System (EIS) unit to the IBBS power-up test list, and then get back to finishing up the electrical system install.
