HEy guys, I always wondered what would happen in this situation. If you go to jump-start a car, and you get the running car hooked up, and then you go to hook it to te dead or dying battery. And you put the positive on the negative and the negative on the positive. What would happen to the cars?

 

i would say FRY everything computer/alternator/relays/radio & everything else

oh yeah ---the battery may explode too[:@]
