I just went out on sent 650 dollars on a smittybuilt x20 10,000 lb. winch for my TJ. I have not yet put it on but have come up with the bright idea that i wont be ableto use it without upgrading my altinator, do to the fact that it has a 500 amp draw. does anyone know any thig about this? do i need too spend more monet just to use this thing?
