all of them were not tight.
in review you will see that I tightend the nut in front of the alternature that you said is the nut for the bolt in which the threaded rod attaches. This is on the bottom of the Alternator.
The one at the top of the alternator that the whole thing pivots on was tight.
One on the bottom back that was tight must have been a mounting bracket bolt for the slide/grove part of the adjustment system. It paralell to the bolt head with the rod attached but closer to the engine.
Now did any of that make any since hehehe
