A good alternator should be putting out 14v at the battery, would be a good place to start checking security of wiring and earths.

If at first you don't succeed, destroy all evidence that you tried.

Sounds like the voltage regulator which I think may be built into the alternator depending on the age of your vehicle. This is potentially a dangerous thing to have happen as over-voltage can totally screw the ECU. You don't want to know how much an ECU costs!
I would get it checked before you use it again.
