First off, what car do you drive? Is it the Accord which you have stated in your profile or any other car? Generally the alternator has a little bit of resistance (could be because of the winding and stuff) otherwise it should roll free.

I also try to work on my car as much as possible and take the help of this manual specially for the Accord automotix.net/autorepair/diy/honda-accord-repair.html. Just take a look and you might also find this quite informative.
