My friend was trying to fix the latch on my car's trunk. The car has a new battery, and was starting fine a week before. As soon as he messed with the latch, the car would not start. The lights on the dash won't even turn on. Could it be that he shorted the car in a way that would not allow it to turn on (even though he only touched the trunk latch)?
If he didn't disconnect the battery before doing any wiring work, I'd say yes. You need to check which fuse blew.
