B206b transponder and ADF not powering up

Sometimes the B206 transponder and ADF radio do not power up when I turn on the avionics. The two GNS units power up fine but the transponder and the adf radio are dead. I think that I am doing it the same way each time but sometimes it works and sometimes it doesn’t. Any hints?

I’ve been having that issue from day one. They seem to work when they want to, and it all happens randomly when loading. It seems like they work nore than they don’t but no I still have not figured out why there’s no power sometimes. Loose wire lol

Happens on the H125 as well.
