As I try to finish up avionics install, I ran across these issues and would appreciate any help.
The only error message on the GDU460 was no info from the magnetometer but that is understood since it is not connected. Since it’s a terminal end, there is a 120 ohm resister across the canbus. No heat on that resistor. No issue.
Issue #1 - G5 won’t sync with the GDU460 for Baro although it did on the bench. No error message on the g5 and it is getting ARINC429 data And the GDU 460 is seeing the LRU.
Issue #2 - A 120 ohm resistor across the canbus on the other terminal end which is the roll servo. That resistor is getting really hot. It’s a small resistor and may be too small so it is heating up. Just guessing.
Everything seems to be working except the baros won’t sync between the G5 and the GDU460. And I’m concerned about the resistor heat on the roll servo term end. Neither of these occurred before I did the final install.
I’m wondering if there is a canbus issue going on. The only change is the forward top skin was riveted on which moved some wires around and he GDU460 was removed and reinstalled.
Suggestions?
