Recently bought a 93 that had been sitting for about 5 years. Had the carbs cleaned and balanced and the front brakes bled. The mechanic said that the cooling fan wasn't coming on and traced the problem to it not being plugged into the junction/fuse box. He said that there was nowhere to plug it in so it must have the wrong box. He said it should be okay to ride it until I got the correct box. I got it registered today and rode it to the gas station to fill it up. It ran fine until right before I got to the station when it sputtered a couple of times then died as I rolled into a parking space. I put it in neutral and hit the starter and nothing. I then noticed that there was no juice to the system. I turned the key off and on a couple of times and the juice came back and it started but ran rough and only revved a little more than idle when I noticed the tach was jumping between 6-7k, then it died again. I called the mechanic and he said he thought it was related to the junction/fuse box. My question is what do you guys think it could be? It might be why it's been sitting for 5 years and why I got it for $700. Also it has a brand new lead acid battery.
