Boondocking - power transfer switch (DC to AC ) quit working

We were under generator power last night when the removable key to the battery disconnect switch vibrated out and afterwards, the auto transfer switch (that switches trailer to AC power) will not work...

The relays are controlled via the circuit board, not the power directly. The circuit "looks" at the generator output and determines if it "likes" the generator output, and then pulls the relay. Still might be a generator issue of over or under voltage.
