Ah polarity... a new find for my assistant.
 

Hi folks, I have a new kid at the shop who I had move some cars.. simple enough right? well, he put the battery charger on reversed direct to the battery in the trunk and although nothing major happened, now, the car has no spark. I don't see anything apparent thats popped. Any Ideas as to what the first link is that would go boom, pow, broken?

Cheers

PS. I used to be a member, I had to rejoin and the system said I have never posted here... MMMM???

Well, aside from the new kids head. If it all seems normal with no obvious open links. Cranks no start no spark given those circumstances. Just taking a pure guess stab at it I'd say the factory smoke got released from the ecu. Do you have a known good spare to check it out with (or swap off of another working vehicle)?
