Had to move my boat the other day due to painting my place. Went to back up and brakes(disc) locked up. Also while attempting to back up, my spotter told me my rear passenger lights on the trailer were out. Brakes, turn etc. Used the tool that came with the trailer to get it backed up. Haven't had time to look at it until this weekend sometime, but is it possible the problem could be associated with the lights being inop? Thanks in advance!
