Hi everybody, I just finished rebuilting my b6ze short nose of my 1990 and I have a problem now, everytime I plug my battery the main fuse (80amp) blows....

I tried removing all the fuse from the fuse box, it still blows....

the main wire from the battery to the main fuse is fine, no short on this one

But I have a question, when I reinstalled my wire at the back of the engine, I got confused about 2 black wire with orange strips, I don't if both really need to be connected to the intake manifold






so, that mean I have a live wire that is grounding itself somewhere....

I already check the alternator and starter, now I'm gonna try it without the alternator plugged in, then without the starter.......

Does anybody would have an idea about what this could be....

Plus, whats are the white live wires that coming out of the fuse box, just after the main fuse

thanks

-Marc-André

Did you put the ground that goes from the engine directly to the chassi on the other side of the car?

I found this link http://midget77.files.wordpress.com/..._elektrisk.pdf
from what this diagram shows me, +12v is feed from the battery, the line is ran to the main fuse box, it is tapped before the main 80A fuse ( for a few circuits this would not make tour 80A fuse blow), on the other side of the 80A the power is split again 4 times . now since the these 4 taps are fused this should not be the problems as they are a lower rating so they will blow before the 80A ( unless this have been bypassed with a wire or solid piece of metal)
so this leads me to think the issue is in the fusebox itself ( a short) or someone has altered the wiring at the main fuse box..

I would unhook the +12 and start testing for short in the fuse box itself remove the fuses and check everything.This seems the logical place to start to trouble shoot.

I know you just rebuilt the motor, so some wires could have been really screwed up on re-installation ( a reverse feed) or some wires were piched causing a short..

I am an Electrician and a electronics engineering technologist by trade, so I know about finding faults in cirsuits.. it is difficult to do so over the internet.. but good luck and if you need any further assistance feel free to ask.

That's what I was planning to do tomorow, for myself, I'm a student in electrical engineering, so I still have alot to learn.
