How To Bypass Voltage Regulator On An Alternator?

If you have a car, you know that the alternator and the voltage regulator are some of its most essential parts. It’s what powers your lights and radio while your vehicle is running. 

How To Bypass Voltage Regulator On An Alternator? You can bypass a voltage regulator with the help of an alternate regulator and connect it to the battery. You will also need the plug harness and the wires to connect the regulator from the battery. 

If you didn’t know, an alternator converts mechanical energy into electrical energy, and a regulator stabilizes the current in the car. If something goes wrong with your alternator, you can have problems with charge levels in the battery. 

Depending on what’s wrong with the system, it may also cause damage to other car components like headlights or speedometer functions. The most common issue with alternators is that of a loose belt.

The belt keeps the rotor spinning while you drive; it will continue to spin without a proper connection. 

This won’t cause issues with charge levels in the battery, but it can potentially damage other electrical parts in your car because of excess voltage when charging. In most cases, all you need to do is tighten the belt or replace it if necessary. 

However, if this doesn’t fix the problem, perhaps you have an internal wiring problem that needs fixing

How Can I Test My Alternator Voltage Regulator?

You can test the car’s voltage regulator by connecting it from the multi-meter. The reading on the multi-meter will decide if you have a bad voltage regulator or not. 

If the voltage regulator of your car is tested and found to be bad, you will have to buy a new one. You can test the voltage regulator by connecting it from the multi-meter. 

First, make sure that you connect it correctly. 

The correct way is that you should connect one wire from the positive terminal to the ground, and another wire from a negative terminal to the positive terminal, for your multi-meter ready volt gauge reading output on the meter needle will be 12 volts. 

The multimeter is a helpful instrument that can be used on many different occasions. 

The steps to test the voltage regulator are:

Step 1 – connect the multi-meter with the car’s battery

Step 2 – Start the engine and check the reading; the reading would be around 12V.

Step 3 – Rev the engine, and if the reading fluctuates, then got a problem in the regulator.

The location of the voltage regulator varies depending on each type of car. Some are located on top of the alternator, while others are located at its side or bottom part. 

How To Bypass PCM Voltage Regulator?

To Bypass the PCM Voltage Regulator, you would need the proper tools and the knowledge of bypassing it. First, you should take your car to the garage for Bypassing regulator. 

The steps can be confusing for beginners; thus, if you do not have any idea about the car and its component, take the mechanic’s assistance to get it done for you. 

He will bypass the regulator properly without damaging any other electrical component of the car. But if you are experienced, you should know that bypassing the regulator requires an alternator. You can get a good aftermarket alternator to get your job done. 

Follow the below steps to bypass your PCM Voltage Regulator: 

  • Step 1 – Open up the car’s hood to locate the voltage regulator. Always bypass the voltage regulator while the engine is cool to prevent the burning of hands. 
  • Step 2 – Now it comes to taking all sources of power down. Detach the black and red wire to ensure that power is not running through the regulator. 
  • Step 3 – After finding the regulator, connect the alternator with the socket. If you are getting confused lookout for the rectangular socket and the wires to connect the alternator. 
  • Step 4 – Correctly connect the alternator with the voltage regulator to run the entire system. Also, make sure to tape the extra wires coming out of it for safety, as you do not need them now.
  • Step 5 – Now connect the fuse box with the regulator switch. Next, you have to connect the fuse box to the 12V key. And now, after all the connections here, connect the wires with your car battery. 

This is it now you are done with your bypassing process. If all the wires are appropriately connected, and tight, you would successfully bypass.

Installation Of Alternator Voltage Regulator

Fault in regulators might seem like an insignificant problem at first, but after some time causes a number of inconveniences. These malfunctions can range from bad headlights to, in extreme cases, emergency vehicle lights that don’t work correctly. 

The installation of the alternator Voltage regulator has several advantages over the faulty regulator. Thus installing a new voltage regulator is best because first, it will give more power to the battery, which means better traction on snow or dry surfaces than before.

Additionally, it will allow you to use electrical devices like heated seats, Bluetooth headsets, and navigation systems without worrying about draining your battery too much. 

Second, these steps can help avoid destroying your motor once out riding in deep snow with thick slush due to poor electrical system design, which would require replacing costly parts like spark plugs.

Frequently Asked Questions

Can I Bypass Voltage Regulators? 

Yes, you can bypass the voltage regulator in many ways with the help of the alternator. 

However, it might be possible that by bypassing this device, you can charge your car faster if it doesn’t have one that isn’t working correctly or is defective, so there may be some benefit to doing this. But first, you would need to set it up.

What Is A Voltage Regulator?

Voltage Regulator is responsible for keeping the AC/DC voltage steady at the desired level. If the AC or DC has too much voltage, the regulator will readjust it to meet its standard. When there’s not enough voltage, this regulator will stabilize it until the desired level is reached again. 

Voltage Regulator Replacement Cost 

The Voltage Regulator replacement cost lies between 250$ to 350$. The new regulator costs about 50$ to 100$, and the labor cost is about 200$. The price of replacement will also depend upon your car and its model.
