Rig Buzzes in Morning after Night Outside

I have not found a root cause yet. When I take down the rig, pull both boards out of the pineapple can, and then reinsert, the keyer will boot properly. Until then, there's just an audible buzz, no radio signal, and the keyer does not boot.

After finding a few drops of water on tape unwrap, I originally though this was a water isseu:

However, better taping didn't seem to help. Also, the keyer begins to operate correctly as soon as it's removed from the can, but not before, and it's operation is independent of drying time.

Yesterday 23/9/30 I found that the power ground connection was exposed due to wahi tape de-adhering from enclosing electrical tape. I replaced the wrapping with only electrical tape, but I'm still seeing the same issue on the morning of 23/10/1.
