If the voltage regulator is defective then yes that will turn off the charging system light when you install a new one. Most voltage regulators are built into the alternator on modern cars so you have to replace the alternator. Have your charging system tested at any auto parts store. Most will do it for free.

Where is the Nissan 200sx voltage regulator located?
The voltage regulator is attachd to the alternator. It bolts on the alternator itself. If you ever replace the alternator, dont make the same mistake I did and not remove the voltage regulator because they are not sold as a whole unit..
Where is the location of the voltage regulator on a 2008 dodge ram 1500 truck?
The voltage regulator for the alternator is in the computer. If the voltage regulator in the computer does not work, you can add an external voltage regulator and then your battery will charge normally. Make sure to check the ground on the computer. If the ground is bad on the computer, then the computer will not regulate the voltage to the alternator properly.
What causes over voltage in a car battery?
A bad voltage regulator in the alternator. Depending on year make and model it may be outside or separate from the alternator.
What would make my battery go dead after replacing it and the alternator?
The vehicle should ave a voltage regulator. If the battery and alternator are good then the regulator is most likely bad.
How do you hook up a ford internal voltage regulator?
To get to an internal voltage regulator first disconnect the battery ground ( negative cable ) then remove the alternator. Make sure you mark the cables on the alternator so you can put them back exactly where they are supposed to go. The voltage regulator is inside the alternator and you will have to take it apart. I'm not sure how the regulator is mounted in your alternator, it might have small studs with nuts on them, or small screws or bolts, or it may be soldered in. In the latter case you will have to cut out the voltage regulator and solder in the new one. If you are going to take out the alternator anyway you should probably take it to a parts store where they will test it for free and tell you if you need a whole new alternator or just the voltage regulator.
Where is the voltage regulator located on a 3800 V6 engine?
What make? What year? If it's a carbureted engine, the voltage regulator is likely integrated into the alternator (some are serviceable, some are not). If the engine is fuel injected, the engine's computer usually serves as the voltage regulator.
You replaced your alternator in your 2000 dodge intrepid but your battery light is still on so you put in another alternator and the light is still on what do you do?
Use a tester to see if the charging system is working properly. If your model has a separate regulator make sure it is working properly. Make sure that your battery is ok, a battery with an internal short can cause the charging light to stay on. The engine computer is the voltage regulator.
What does check charging system in a 2007 Ford Taurus mean and the battery light is on and the steering wheel won't turn?
Usually the voltage regulator is the problem. Its located inside the alternator. More testing is needed to make sure that the regulator is the fault. If you want to guess. Replace the alternator. Sounds to me like the power steering and alternator belt has fallen off.
What would cause the voltage gauge to keep flickering up and down?
Either a bad ground to the guage itself or a bad voltage regulator in the alternator. While the enigine is running check the voltage at the battery it should be around 13.5volts if it constantly fluctuates then the voltage regulator is probably bad. Replace the alternator. Otherwise make sure your grounds are good.
What is a voltage regulator within the alternator?
Depends on the alternator,,, what is it on,?? I can't believe the people that don't state make, model, year and engine size before posting a question.
Why would a 02 Toyota celica gt battery light come on checked the terminal connections and every thing is tight it always starts sometimes light goes out What else can make the light come on?
The voltage regulator inside the alternator will malfunction. Often, all the warning lights will come on: brake/batt/etc. Replace alternator.
Why do the voltage battery light keep coming on after a new battery has been installed?
Ah, you have made one of the most common and easiest mistakes to make in automotive maintenance. Because the 'battery voltage' idiot light came on, you assumed that the battery was bad. Did you have an automotive electrical specialist test the electrical system on your car? Did you have the battery tested at a battery shop? Did you know that there are 3 primary parts to an automotive electrical system, and anyone of them can be responsible for the system operating below required voltage levels? Most modern automobiles generate electricity with a device called an alternator, which is driven by a belt from the crankshaft. The alternator generates Direct Current, at voltages up to 20 volts, in some cases. To keep the alternator from frying the battery, a Voltage Regulator is used to control the output of the alternator. This insures that the battery is only charged with a current of 18 volts, or less. Most modern alterators have the voltage regulator inside, but on older cars, the voltage regulator is mounted on the fender or the firewall, somewhere in the engine compartment. So, the alternator generates the electricity used to charge the battery, but the voltage regulator controls the output of the alternator. If the alternator is going bad, it may not be generating enough voltage to charge the battery. The battery is usually a 12 volt battery, and must see more than 12 volts to charge. Or, the alternator output might be reduced to an unusable level by the voltage regulator. Before you replace the entire electrical system, take the car to an automotive electrical specialist for testing. They can determine exactly which component is not working, and repair it. (Note: If the voltage regulator is bad, this DOES NOT mean that the entire alternator must be replaced! In almost all cases, the voltage regulator can be replaced by disassembling the alternator. If the specialist insists that the alternator must be replaced, I would recommend getting a second opinion, even though testing is often not free. Voltage regulators are fairly cheap, and can be replaced by a competent technician without too much difficulty. Alternators are expensive.)
