65 coupe - Voltage fluctuation

My voltage fluctuates between 14 and 16 volts with interior and headlights on at night. I wouldn't have really noticed except that it makes my headlights and all the other lights in the car pulse (like someone is playing with the dimmer switch) over a 2 second period... Is this normal? Is it a bad volatge regulator or Alternator?

It seems likely to be the voltage rgeulator.
It should not allow that much voltage to generate at any given time.
However, I would try that before spending the $$$ on an alternator.

Good Luck!!

Ya, I would start with the regulator.
