According to ASK.COM, a voltage regulator on a car is “a car component used to maintain a consistent voltage output. It acts as gatekeeper by shutting off the flow of energy to the car’s battery once the voltage goes above a certain level. ” [SOURCE ARTICLE]

Why do you need a voltage regulator? Well, if the flow of energy to the battery isn’t controlled, too much or too little power can be delivered. If too little power goes to the battery, it will eventually be drained of energy. If too much power goes to the battery, however, it can literally cause the battery to explode. A voltage regulator is one third of your car’s electrical system. The other two pieces are the battery and the alternator.

How Does a Voltage Regulator on a Car Work?

Working in conjunction with the other two components of your car’s electrical system, the voltage regulator controls the power flow. Your alternator produces power and then charges the battery. The battery in turn powers the car. Between the alternator and the battery however is the voltage regulator. So all three components work in harmony.

Every three years its a good idea to replace your car battery. You want to replace your alternator after every third battery replacement. As for the voltage regulator, there is no rule of three. You just replace it when it goes bad. And how can you tell when it has gone bad? That’s a bit harder. It mirrors the symptoms of when a car battery goes bad. Your car won’t start for example. If you have any sort of electrical problems, be sure to get your car into an auto mechanic to fix it.

This concludes part three of our series. For more information on electrical problems, be sure to read part one and part two as well.
