A positive to positve, negitive to negitive jump start can melt all of the wires in your cars electrical system and damage the alternator. That's the worst that can happen. If your lucky, all you fried were the battery connector cables. Replace them and see if you get power. It the car still has no power after replaceing the cables, test the alternator. If it's bad replace it, if not your electrical system is probably toast. Goog Luck!
