The voltage regulator is now part of the main PCM or computer instead of
in the alternator.

The buzzing noise is typical of a relay that is bad or shorted out.

The alternator pinning out the voltage gauge can mean a short circuit
someplace or even a short in the alternator.

I think I would go looking for the source of the buzzing first and
address that, then maybe try starting it with the alternator unplugged
to see if it's a shorted alternator.
