hey guys,my brother has a 03 sportsman 600.he put a winch on it,now the battery wont charge.he thought maybe it was a junk battery so he bought a new one,that battery is dead now after 1 ride and trying out the winch.i havent looked at it yet so i dont know how the winch is hooked up,what do you guys think the problem is,a bad ground?he was asking if there was anyway to put a pullrope housing on it?im not sure about it so im asking you,thanks for any help.
