Supercharger not engaging IC pump changed month ago

Started her up this morning and heard some squeaking noise from the supercharger pulley. Went for a drive and noticed the supercharger is not engaging. Is my clutch toast? If so where do you get OEM ones?

Drove it around a bit and noise went away, Still need to take belt off and spin by hand. Don't think a bearing would cause it not to engage. I noticed the supercharger chirp disappeared while driving too. It is a bit colder outside.

So I just went out there to check everything. The black portion behind the clutch, spins freely when the car is off, Should it do this? Bearing needs to be replaced? There was a bit of noise when I spun it. No belts were removed.

Bearing has noise when spun, but this shouldn't cause lack of engagement? I disconnected the battery and the chirp came back, but now its gone again.

The fuse more than likely popped. I forget which one it is but its in the trunk.
