Im actually not sure why you took out a fuse to the alt and then connected it.. When you take that fuse out. your instantly open circuit and have no connectivity between the alt and the battery even when the cables are connected... Obviously if there is a spark coming from the terminal there is some sort of charge coming from the cable... Also are you sure your battery is not bad ? On my s13 ka24e-t my battery is so dead that even after i drive a couple miles it wont hold a charge.. some batteries will just not hold a charge for longer than a couple hours..
