Loose BAT terminal on alternator - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I have blown the maxi fuse from my alternator to my block on the wall upon startup of the truck. I checked he wire and followed it back to the alt to find the BAT stud kind of spins when I'm trying to tighten down the connection. Could this be shorting out that circuit? And if so, is there a way to tighten that BAT stud without having to replace the whole alternator?

It's a double ended stud that is supposed to be held by the isolator. Here is a blog post on how rebuild one. http://tc.wagoneer.org/2012/08/delco...ild-guide.html
Take it apart they are cheap and simple. If you have to replace it look for a 94 amp one off of an 84-85 Z28.

The one I have right now is a 140a summit racing unit.
