Voltage Regulator Shopping Info

What Is a Voltage Regulator?

Voltage regulators maintain the voltage coming from a power source by keeping it at a specific range to prevent it from damaging electronics. Automotive voltage regulators are responsible for making sure that power from the alternator doesn’t damage the battery. They also regulate the amount of power that the alternator creates.

How Much Does a Voltage Regulator Replacement Cost?

A replacement voltage regulator can cost anywhere from $10 to $290. The price largely depends on the regulator’s design and your vehicle’s make and model.
