Hi Art,
I think it might be a case of belt and suspenders but in the industrial arena,
it is not uncommon for vendors implementing CAN networks to recommend twisted
+ shielded cabling.
https://www.belden.com/hubfs/resources/technical/technical-data/english/773105T.pdf?hsLang=en
Granted, an airplane is not as electrically noisy as a modern manufacturing site
but as I expect the more learned contibutors to the forum will advocate, following
the vendors recommended installation practices is usually good advice.
Best regards,
Dan.

Yeah . . . probably . . . but about the only way
you can buy twisted pair is under a shield. I've
probably got a few thousand feed of 2x22S . . .
how many feet do you need . . . send me a mailing

Thanks Dave and Charlie. I had a chance to go to the hangar briefly, so I checked
the where the tray is placed. It is actually slightly proud on one side
and even on the other. I noticed the panel screw was slightly loose so I tightened
it , but that didnt fix the problem. Ill have more time tomorrow so Ill
check out the pin depth placement. I had the back of the tray off to get a
pin in for the position source for the ADS-B out transponder. That may have
have moved the pins adversely.
Thanks again!

power supply and it turned on just fine. Sliding the radio back in the tray and
turning it on there was nothing. So my question is: If I replace the female
power and ground pins in the 37 pin dsub will that take care of the problem?
I am thinking there is wear at the pin-socket junction. Is there something
else I should look at? I have had no problems with the tray and the radio prior
to this, so I am looking for some one who has solved the problem before.
The plane and radio have 902 hours of use.
