Can I drive my car with a bad voltage regulator?
A bad voltage regulator may cause it to simply not work or behave erratically. You’re not likely to be able to start the car at all, but even if you could, it wouldn’t be wise to do so without knowing how fast you’re driving, how much fuel you have left, and other critical info.

Dead Battery A burned-out voltage regulator will diminish the vehicle battery’s ability to charge or stop it altogether. If the battery is recharged, the vehicle will start, although the faulty voltage regulator will only cause the battery to lose power rapidly.
What causes a voltage regulator to overcharge?
Improperly jump-starting the vehicle can send a surge through the battery that destroys one or more cells in the battery or shorts it out. This surge disrupts the wiring in the alternator, causing an overcharging condition.
What can cause a voltage regulator to go bad?
A battery that is not holding a charge can cause the voltage regulator/rectifier to fail as it charges at maximum output constantly trying to bring the battery voltage up; fully charging the battery then running a load test will reveal if the battery is breaking down under load (and this can be a problem even with a new battery).
Can voltage regulator cause starting problems?
The voltage regulator is responsible to assure a proper voltage when charging the battery. The only case when the voltage regulator keeps a car from starting is if it was faulty and the battery was not charged. Because of this issue, when the battery is drained, of course the engine will not start.
