Those numbers indicate no charge at all. If I remember right, you should be getting about 13.52v @2500rpm with minimal load.

Hopefully you have the problem Steve describes, because it is cheaper to fix...

...though your alternator could still be toast.
When my alternator failed, the battery light did not come on either, but replacing the Alt fixed the problem, so warning light circuit was fine.

Best of luck.
