1973 280-C Generator Light Flashing

With a new alternator, voltage regulator, and battery installed, the generator light starts flashing on/off when car is driven over sixty-five MPH. Otherwise, all is normal. Does anyone have any ideas as to why?

Still sounds like a charging system problem. Try connecting a volt meter & watch the voltage spikes when the light blinks. Have someone else drive.

Did you check belt tension? It might start flopping around at high-rpm and begin slipping. It happened with a VW Vanagon I used to have.
