Re: alternator not supplying power to car, battery is.
The battery supplies the power and the alternator is designed to maintain the charge in the battery. If you have an alternator on your car, you do not have a voltage regulator. Voltage regulators are used with generators.
If it was me, I'd replace the battery and alternator.
