Please help Me.."Overcharging"?

For some reason when I went to pick up my new alternator. I had to remove one of the terminals off of my old alternator and put it in the new one.
I guess that is the brush on the springy thing that comes out.
I don't understand why it was missing one on the new one??
I just removed that old one, and it was not sticking out far enough to touch where it needed too, and also fell apart.
I!
