how long was it hooked up?? Only way a diode should be harmed is if a substantial load has been been tried to be put through it.

What needs to be done is to disconnect one of the batteries on the ground side THE BLACK ONE LOL, then recharge each battery by itself, if it was a good charger then it wouldn't have done anything as they have a feature to not allow it to work if hooked up backwords.

I understand if you have a regular charger from sears or other then alot of times they won't charge 2 batts very good, what I do is charge each one seperate untill fully charged then after I hook them both back up I will start the truck and let it run for at least 15 minutes, it basically just helps make sure the batteries are ballanced and not bucking each other. Keep in mind if one battery is bad then BOTH have to be replaced, it is cheaper in the long run because the new battery will only last as long as the old one if replaced one at a time.

My jumper pack is like that. If hooked up backwards it trips off line. If hooked to a totally dead electrical system where it can't sense if it is hooked up right you have to push two buttons simultaneously to bring it on line...

Hopefully the OP's charger works similarly.

Agreed, hopefully all it did was nothing at all. If it's a newer charger I'm sure it wouldn't work that way.

I once hooked up an optima red top backwards in my gf's escape (felt like a complete jackass that I messed up such a simple chore, talk about embarassing). That was fun. Car was 100% dead. Fried a relay. Had to have it flat towed to the dealer to have it replaced, as it was 10 degrees out in the wind and I didn't feel like tracing it down. Good times.
