My friend hasa problem and here is what he wrote :

1991 Honda Accord LX
Heres my problem.......I gave this kid at work a jump and his hood doesn't stay up by its self so he let it down and it fried sumthing in my car. The next day I replaced the ground wire that leads from the battery down next to the starter, and the car took a jump I let it run for about an hour then shut it off and its like the car had no juice, no lights, no nothing. So I figured it was the battery, bought a new battery and when I hooked it up the main fuse blew, I had another one in the car and tried that one too and it blew as soon as I touched it with the screw driver. Now I am guessing that there is a short sumwhere but I have no clue where to start and I am open for any suggestions.

I'm thinking it a bad ground or there are some wires touching, any ideas would be great. thanks

 

Nobody has a clue? Anything would help.

 

It sounds like your friend managed to complete a circuit through this dude's hood or frame. It's the same as touching the jumper cable contacts together while it's hooked up to your car.
From past experience, I'd start by checking your wire harness. It sounds like you overloaded the voltage regulator. If your voltage regulator fries, nothing protects your wiring. It also allows WAY too much juice to reach the main fuse, which would cause it to blow. I'd also check your alternator to see if it's charging correctly. You may need to replace it.

 

Thanks, I'll let you know if we have any luck. peace
