The battery is new I bought it but never put it in. I actually junked the car it was supposed to go in. It has just been sitting on my work bench for about 4 monthes.

The reason I think it could be a bad regulator is I was getting 14 with the old regulator but all my idiot lights were on so that's why I changed it and the brushes were worn. All of the other issues started after I changed the regulator. So it could be a bad regulator or was the alternator on the way out and by changing the regulator it finally just crapped out.
