Please help Me.."Overcharging"?

Okay, It got stranger.
I ran two new wires to the VR. The old ones seemed brittle. I put new connectors on, and everything.
Now, it quit charging completely.
I did leave out one thing.
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 am going to take it back and have them test it, and I am sure it won't charge. They need to get me another one, and have both new terminals on it, and actually work.
Why it was overcharging...I have no idea....Now....no charging...ugh!

This is what I was wondering about when I posted the other post about being grounded to the case.
