=EF=BBHello all,
At times it seems like it=99s one step forward and two steps back. So
it went for me this past week. I thought I was finished with my panel upgr
ade and took the plane up for a test flight. Keep in mind all the component
s were working prior to the final install in the panel.
I enter the flight plan in the 175 and it comes across to the Dynon, great.
I take off and note that the magenta line isn=99t being displayed on m
y moving map, nor is the HSI working properly. I am also getting an error on
the G5 for loss of ARINC429. I get back down and check the setting they se
em good. What=99s going on? It was all working fine before the final i
nstall. I check the Dynon diagnostics and see ARINC labels coming across, y
et no HSI, odd. I email Dynon, they scratch their head and can=99t fi
gure it out, settings look good. Maybe the Dynon doesn=99t like to pl
ay with the G5, and they suggest disconnecting it from the system, even thou
gh I told them it was working previously.
Frustrated, I head out to the plane and remove the center panel to gain acce
ss to the G5 and GAD29 which required that I remove the com radio and GPS. I
go to reinstall the GPS in its tray and something doesn=99t feel righ
t. I pull it back out and peer inside the tray and that do I find, a bent p
in in the tray connector. Ugh. I confirm the bent pin is for ARINC out. T
hat makes sense.
Optimistic as ever I think I can straighten the pin while in the tray. Who w
as I kidding. I had to remove the trays and wiring harness from the plane.
What a PITA it was. I replaced the pin which was no small feat. Then I re
connected the harness and did a quick functional check without the trays and
everything worked. I then move on to reinstalling everything into the pane
l. As I was installing the trays I found myself pushing against the pins i
n the connector. Fortunately, I realized what I was doing and stopped befor
e bending any more pins. Mystery solved. Those HD pins are tiny and very, v
ery fragile.
Here's a picture of the panel upgrade which is complete for the most part.
