I am not sure what you mean by "the pole was underwater".
Are you talking about the place where you plug in the camper?
Have you tested the outlet (the one you plug the camper into - it is possible for that one to be bad, but the one next to it to be good)?
Have you tested (with a multimeter) the voltage available at the pole?
