MRC AD520s, they're relays powered off the DCC bus. Normally, they don't
make much noise at all, but after this problem occurred they've been
clicking every 4-5 seconds.

No beeps.

I'm certain, without looking, that the wire is in place. There was a
note next to it explaining how to do that. I will check the grounds
Thursday.

I'm not sure about that. Apparently the layout was supposed to be broken
