Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.

That would tend to indicate a problem in the cord plug or at the J-box where all the leads are hooked up OR something shorted out. It has to be getting power from some source. If the batteries are disconnected and the tow cord is too, then that can't happen unless you are plugged into shore power. Is that the case here?
