G3x setup, ADAHRS and Transponder not working

[Billiken]

I was following your thread and I thought you had solved the problem. I may have read another thread with the exact same issue. The fix was that two pins were reversed from the pre wired harness. It may be the same problem, especially if they are both from the same supplier. Just thought I’d mention it. Good luck!

Chances of a bad box are very low.
Sounds like a CANBUS issue.
I can try to help you but I need much more information.
Do you have CAN with serial backup to all available devices?
Do you have the CAN termination resistors in place?
Show the CAN network and electrical diagram.
What does the device connection screen show?
Did you configure the devices properly?

Probably easier to do a video call or something to go through it. Troubleshooting electrical through a forum is very difficult.
PM me if you want to set something up and I will try to help.
