Well it started yesterday as simply replacing the alternator belt, yeah right...
It had been squealing like a pig, (it was loose).
One 3/4 turn on the adjuster bolt and snap! Now i've got a broken bolt in the alternator "ear".
With 90% of my tools still in storage and nowhere to work, (nope, still aint' got the barn built yet).
It's much easier to replace the alternator, than to drill and easy-out the bolt.
Yeah, I've got spare alternators in storage but can't get to them!
Ok, now let's go ahead and replace the alternator, (just in case it was the bearings "squealing" in it and not the belt).
I pulled the original 1971 Motorcraft alternator out of the truck, that was still charging!
After some 35+ years it was still ticking!
Just can't beat Ford's and Motorcraft parts reliability with a stick!

Bet I get maybe three years life from the mexico assembled/lifetime warranty junk I was given?
And, the "stamped" location of the ground wire on the alternator was wrong, the wiring ground strap can't go onto the screw identified as such.
You have to use the "other" screw.
Maybe this post should be in vendor feedback?
Watch your ground strap on the autozone alternator's guys.
