Thank goodness Forest River put in a failsafe against stupidity. When I installed the bracket for the other sway bar it partially covered up the sticker that tells you how to hook up the battery and what the wires are. Well being used to red and black for DC instead of white and red dummy me hooked the battery up backwards. Thank goodness Forest River built-in reverse polarity protection on the converter. I made this mistake one other time on the crossroads Trailer that we had and it fried converter because there was no reverse polarity protection built into that trailer.
