I I don't know how to conclusively diagnose a failing regulator but I'd say that your symptoms are strong evidence that the regulator is dying
Do consider that at these charging voltages the battery electrolyte is being boiled off and has drastically reduced the life of the battery if not outright murdered it.
Google suggests that there is some minor possibility that the regulator can be replaced in situ. I've never attempted it.
it sounds like the unpleasant task of pulling the alternator is in your future. One out of the car the regulator can certainly be replaced.
