Voltage Regulator Guides





Balance plays a critical role in your car's battery charging system. Once the engine is cranked and running, it's all up to the alternator to supply electrical energy to the battery. That's because the battery can't support all of your car's electric-powered systems by itself.To make sure the battery receives just the right amount of voltage, though, the alternator is equipped with a voltage regulator. The voltage regulator cuts off power supply to the battery when voltage exceeds 14.5 volts.If the regulator didn't do its job, your car's battery may become damaged due to overcharging. As power is drained from the battery, the regulator allows the alternator to supply power to replenish the battery's charge.If one day, you discover that your car won't start up despite a fully functional engine and a full gas tank, suspect a voltage regulator. Switch off the ignition and don't panic. Have the regulator checked for voltage and replace if necessary. Carparts has plenty of regulators in stock.


• Keeps the power supply from your alternator at a safe voltage

• Helps prevent damage to your car's electric-powered systems

• Ensures that the battery is protected from overcharging

Helpful Tips to Remember When Choosing the Right Voltage Regulator

Working alongside the alternator and the battery, a voltage regulator is one of the components responsible in ensuring that your car maintains a specific power level that's needed to trigger its electrical components. But more than just supplying the proper amount of voltage, this auto part also helps in protecting the battery from getting overcharged. From your car's radio to its signal lights, the voltage regulator plays a huge role in keeping the electrical components of your car in their proper working condition. Can you imagine how disastrous it would be if it gets broken? Save your vehicle from sustaining an even bigger damage by replacing a faulty voltage regulator as soon as you can. Here are the things you should know before you buy a new one:

Dos

  • Talk to your car's dealership to ask about OEM voltage regulators. Although they may cost a lot more than aftermarket ones, this type is still recommended if you're looking for a high-quality option.
  • If you're planning to get an aftermarket voltage regulator, make sure that you buy from trusted brands to get a product that's proven to have long-term durability and good performance.
  • Consult your vehicle's manual to see the voltage rating required by your car before buying a new regulator. Although the standard voltage requirement for most vehicles ranges between 13.5 volts to 14.5 volts, it wouldn't hurt for you to double-check. Make sure you get a new voltage regulator that meets your car's specifications.

Don'ts

  • DON'T forget to check the capacitors of the voltage regulator. You should verify if it uses high-quality capacitors that meet the ratings required by your vehicle. Keep in mind that even the smallest discrepancy with regards to its capacitance may cause the voltage regulator to fail.
  • DON'T buy remanufactured voltage regulators if the quality of its components is questionable.
  • DON'T dismiss the chances of a faulty battery or alternator. Before you install a new voltage regulator on your car, consider checking the other components linked to it to see if they're damaged as well.
  • DON'T make the mistake of buying a low-quality voltage regulator just because it initially costs less. There's a better chance of getting long-term savings in buying a high-quality voltage regulator instead of settling for a cheap substandard one.

Replacing Your Car’s Voltage Regulator in Eight Straightforward Steps

Have you ever thought about the electrical components behind the operation of your car's various parts and accessories? One of the essential parts responsible for controlling the power of your vehicle is the voltage regulator. It basically lets the alternator produce a sufficient amount of voltage that's needed to recharge the battery while powering up the various devices in your car.

From an overcharged battery to a burnt-out alternator, there are a lot of complications that may stem from a faulty voltage regulator. Dimming lights and sulphur-like smell are the two most common indications that a voltage regulator must be replaced. You can do this as a DIY task in the comfort of your own garage. Here are the tools you may need and the procedures you have to follow:

Difficulty level: Moderate

What you'll need:

  • Screwdriver
  • Wrench
  • Electrical tape
  • Owner's manual
  • Replacement voltage regulator

Step 1: Raise your car's hood and locate the battery. Disconnect its negative cable and use the electrical tape to cover the end. Doing this prevents the possible electrocution.

Step 2: Find the voltage regulator inside the engine compartment. It's usually located near the alternator. You may refer to the owner's manual to see its exact location.

Step 3: Carefully unplug the cables connected to the old voltage regulator. The number of cables attached to it may differ based on the make and model of your vehicle. If the cables are secured with screws, unscrew them first before pulling them out.

Step 4: Using a wrench or screwdriver, detach the bolts and screws that are connecting the voltage regulator to the alternator.

Step 5: Pull the old voltage regulator out and position the new one in its place.

Step 6: Secure the replacement voltage regulator by reattaching in to the alternator with the same set of screws and bolts that you removed earlier.

Step 7: Reconnect the cables into the new voltage regulator.

Step 8: Plug the negative cable back to the car's battery and test if the new voltage regulator is functioning properly.

The whole task of replacing your vehicle's voltage regulator may take around an hour to finish if you're a skilled mechanic. Keep in mind that you'll be dealing with the sensitive electrical components of your vehicle, so make sure to work safely.
