[QUOTE="Bugpac, post: 272572, member: 1862"] I don't believe it is intended to charge the batterys, It is intended to maintain a trailer brake battery, and power a few 12 volt lights. Charging large rv or boat batteries if they are real weak is really gonna tax the stock alternator. They wont last long that way. With a dc circuit, you could run a wire from your tail light and it will charge the battery, Just sayin! Seven blade plug is simple, all its adding is brake wire, backup lights, and the 12 volt positive. [/QUOTE]
