My phat nintendo ds wont charge. The charge light comes on and then goes off within a second. Im really stuck because i dont know what the cause is because my charge cable was chewed by a dog and it has lots of holes in it. So i dont know if its my ds or the cable. :'( i have heard of phat nintendo ds just stop charging all of a sudden and its not fixable not sure if thats whats wrong with mine. So my question is will i be wasting my money if i buy a new cable.
