If it becomes weak for some reason, it will not supply the right amount of power. The main topic we are talking about today is alternate overcharging. It is a common problem in almost all automobiles. You can face alternator overcharging for many reasons.
Some problems are mechanical, and some people cause issue by mistake. So far, you have known the reasons why alternators are overcharged. Obviously, it is a big issue for automobile users. And they need to find out this problem. To find out the problem, they need to learn about the symptoms. Alternator overcharging symptoms are concerning issues for automobile users.
If we face this problem, we should solve it as soon as possible. Otherwise, it can occur damage of our car engine and other parts. There are many ways to solve it. There is not only one reason behind this issue. The swollen battery is the most common sign that tells your alternator is overcharging. The battery electricity level should be normal. Excessive charge from the alternator makes your car battery lose electricity.
The battery lost the ability to hold an electrical charge over time, and eventually, the battery lost more electricity. If you properly give attention to your car battery, you will notice something that will tell your car alternator is overcharging. For various causes, your car alternator can be overcharged.
Some of the most common causes an alternator to overcharge are battery fault, Voltage regulator in your car, and Alternator size. Also, if you jump-start your car in an improper way, this can also overcharge an alternator. Knowing only the reasons why your alternator overcharging is not enough because you have to know more details. The external regulator or voltage regulator work is to force the alternator to maintain the voltage.
The external regulator transforms your car alternator into a three-phase charging system. The external regulator has the ability to modify the alternator charge profile. It modifies the alternator charge to match the right battery charge time and battery life. By three electromagnetic contact switches inside of the housing, the voltage regulator can open and close. So, contact switches have a big role in the external regulator. If voltage regulator electromagnetic switches get stuck or not working or disengage, it will produce an overcharge to the alternator.
And this is how the voltage regulator can cause the alternator to overcharge. An alternator can overcharge for an incorrect replacement of your car battery. The modern car owners are facing more battery incorrect replacement issues in their cars because the modern car needs signals from the electrical control unit.
So, eventually, the alternator will be overcharged, and also the battery is going to be very hot. Alternator overcharging does not only damage the alternator itself. An overcharging alternator also damages the battery. If your alternator overcharges, it will produce more voltage to the battery and make your battery very hot, and eventually, the battery will lose the electrolyte.
If you jump-start your vehicle, make sure you do it in the right way because an improper way of jump-start can lead your car alternator to overcharge. Improper jump-start the car can supply surge through battery cable which can damage or destroy battery cells. And this surge also shatters the alternator wiring. When alternator wiring is disrupted, the alternator is going to overcharge.
Battery cells can be fixed if you know the appropriate way to fix battery cells. The internal regulator has one wire which is connected with an external regulator aka Voltage Regulator. Internal regulator wire helps the external regulator to operate the alternator from the outside of the box.
If the internal regulator is not regulated properly, it can produce excessive charges to the alternator. As a car owner, you will need to replace and install the alternator in your car. Whether you or a car mechanic replace the alternator, make sure to install an appropriate alternator for your car—an alternator that is appropriate for your car model. You need to remember that some alternators can provide a huge amount of voltage, which can be excessive for your car.
When you put the wrong alternator in your car, it will supply higher or less charge, which can cause alternator overcharging. Always avoid putting the wrong alternator in your car. These are the reasons why your car alternator is overcharging.
After you find out why your alternator is overcharging now, you need to fix the overcharging alternator. Some replacement and re-manufactured alternators have much higher output ratings and designs. When the wrong alternator has been installed in a stock vehicle or if the pulley has undersized dimensions causing extra alternator rotation , the charging supply will be higher than the demand and cause an overcharged state.
High performance or racing alternators should not be installed on stock passenger vehicles. The external regulator, usually mounted on the engine firewall or fender well, supplies current to the internal rotor field coil inside the alternator. It regulates the amount of electricity that the alternator needs to perform at different speeds. The external regulator usually has three electromagnetic contact switches inside its housing that open and close. A stuck contact switch that refuses to disengage will cause an overcharging problem.
The internal regulator, or "internally regulated" regulator, has been used as a replacement for older, externally mounted regulators. The internal regulator mounts inside the alternator case consolidated , with a smaller and more compact design. If one of the contact switches has stuck, it can produce an overcharge rate, typically 15 volts or more.
The older type of fender-mounted regulator and a newer alternator that has the regulator inside of it will show the same types of overcharging symptoms.
