If you accidentally short out the positive battery terminal through a jump cable on the engine (outboard)<br /> frame, can this damage the ignition or any other function of the electrical system or charging system?<br /> We are talking just a momentary "Spark" not causing wire overheat or anything drastic like that .<br />I recall cars from the '80's upward had a label displaying " Do not short out any ternimals as this will cause damage".
