had to jump a relatives truck when I got off of work the other morning, a Colorado I jumped with my Ranger. It was still dark and I wanted to hurry up and get home, I was tired,(Someone always needs something I need to learn how to tell people no, even in situations like this)so in a rush I accidentally crossed the jumper cables on the Ranger, it sparked and the truck idled down like it was about to die before I realized and pulled the cables off. hooked the cables up right and the Colorado started right up. The Ranger runs fine since, but can any damage have been done to the battery or the alternator or any electrical components?
