You're not charging then. Should be, what, 14.6 volts when it's charging I think.
Yup, it would be.
Three words: "Voltage regulator".
Alternators are a fairly basic electromechanical assembly. The voltage regulator and diodes are much, much more likely to be the failure point. Now, the VR might not be the _root cause_ of the failure, something else may have caused it to go. But, any decent automotive electrical place will be able to tell you if it's the VR or the alternator itself. (if they can't, then they're just parts salesmen).
