Maine Sail....yes, yes!! your diagram is exactly the way mine are wired; the + and - are pulled off opposite ends. Stu's diagram doesn't really show that, but overall, I said mine was wired like that picture. But your picture is exactly the way I did it......so...if the current is pulled from opposite ends, there is no need to "rotate" the batteries to change the flow? Just a thought that came up that made me curious.
