Intermittent Short Circuit 200 1982

We just purchased an '82 244, non-turbo with 121k miles on it. It has had various repairs done in the past. Some appear to be well done, some appear to be done by Yabboes that shouldn't be allowed near tools.

On of the first thing to address was the intermittent stalling. After some research on the board I went to check out the 25 amp fuse by the battery. Fuse? What fuse? Instead somebody had cut it out and done a really crappy butt splice using pliers to crimp with. There was lots of corrosion and the butt connector showed serious signs of overheating. Ahhh, this will be easy. So I cut things back, put a nice marine waterproof fuse hold in, and used heatshrink butt connectors. (I'm a marine electrician so I figured I'd treat it like a boat.) Took it for a 20 mile test drive and no problems. Great.

Fast forward to this evening with my wife in the car. About 1/2 mile from home, bam, no power to anything, leaving us dead, in the dark, at a busy intersection. The main 25 amp fuse was blown.

So obviously I have a short circuit somewhere. I know that there are a lot of places it could be. I'm hoping that maybe the collected wisdom of the board may have some suggestions as to the most likely spots to check first. Obviously it must be upstream of the main fuse block as nothing else blew. It is also clearly intermittent and for the most part is fine. It does not seem to be related to bumps. It has, in the past, cut out on perfectly smooth road.

Thoughts would be greatly appreciated.

Thanks,
Jim
