Stuck Alternator - 2009 2.7L

Hi there, I have what may be a silly question. With this Covid stuff, my truck sat for a few months. When I went to start it the other day, my alternator was stuck and it snapped my serpentine belt. I have been able to unstick it I think. I could feel it let go but should I be able to turn it freely? I can rock it back and forth about half a turn each way but I can't turn it all the way around. Am I out of the woods or is the alternator shot? Thanks

 

Its shot

It should spin freely like a skateboard wheel

 

Yep, it should spin like this. LOL
