Does it engage under computer control or is it static?

Hey guys thanks for the replies. I was able to replace the pulley and belt easily and was hoping that would be the end of this thread however my car wont start now. I believe i installed everything correctly which is why i'm confused since it started even with the belt off.

I thought maybe the battery just died since its been sitting there for about a week, but whenever i hooked it up to my girlfriends car and charged it for about 10 minutes it still wouldn't start. Here's a video of me turning on the car. Here's a video of me trying to turn it on.

My 00' boxster has a little over 100K miles, i'm willing to change the alternator and agree that i probably should. Could this new problem be related to the alternator?

Thank you guys for the help!

If the alternator is not making ratcheting sounds, put a new belt on it and you are done.

Hey JFP in PA..I thought this cap was some sort of dust cover. Are you sure it isn't needed? I am in the the middle of replacing mine as we speak and my Bosch part did not include the cap as well.

This actually happen to me last week. I heard a bit of squeaking from a the pulley and was going to check it over the weekend. Didn't make it cause the following day I actually heard someimg fly off and down the road and lost powering steering. I had towed and it turns out the alternator pulley came off. This alnerator has 150,000 miles on it

The cap is a dust/debris shield to keep crud out of the inner workings of the pulley.

Thats what I thought. My replacement pulley did not come with one and I lost the orgininal. Can this part be purchased separately? I did a search and came up with no luck.
