How Long Does an Alternator Last?

Introduction

If a person wants to know how long an alternator lasts, he should gather some information about the Alternator itself. Electrical current is generated in a car with the help of an alternator.

As soon as the engine starts, mechanical energy is converted into electrical energy. This energy is provided to the different parts of the car for functioning.

For instance, a spark plug is initiated with the help of an alternator. The power the Alternator generates is stored in a battery to be used if the engine is shut down.

Alternator Lifespan

The average life of an alternator is about 6-10 years. The belt’s quality is one of the most important factors in deciding the life span of an alternator. With time, the alternator’s working is affected. The battery starts to run out, and after that, the alternator starts to wear out. If you estimate an alternator’s life expectancy in terms of a car’s mileage, it is around 150,000 miles. After its lifespan, an alternator must be replaced with a new one.

How an Alternator Works

The working of an alternator is a complex matter, different parts of the alternator work in coordination to work correctly. Electrical energy is produced with the help of mechanical energy that is generated from the flywheel. The Alternator belt is attached to the pully, and that in turn attached to the rotor shaft. The name of the Alternator indicates that it produces alternating current as it works. A car requires a DC supply for its parts to be working. AC is the type that is used in a household, but a single battery cannot provide the whole supply. The AC supply current is of no use to the vehicle, so a device known as a rectifier is used to convert AC into DC which is used for running tasks. The lifespan of an alternator also depends on the speed of the vehicle.

Signs of a Bad Alternator

An alternator converts mechanical energy in an engine into electrical energy. Sure, signs indicate that the car’s Alternator is not working correctly. The sign of a failing battery is one of the indicators of a failing lousy alternator.

First, the battery requires an alternator to charge. If the systems in the car that run with the battery start to go wrong, this is a sign that your Alternator is not charging the battery correctly.

  • If the battery light is on, it means that there is a problem with battery charging. The Alternator provides the proper voltage required for charging.
  • Corroded parts of an alternator will reduce its efficiency.
  • Heavy load of the electrical supply will fail in the system.
  • As the Alternator starts to fail, the lights dim. This is a common indicator of failure of an alternator.
  • Sometimes, the car has a burning smell that indicates the fallout of the Alternator. This is because of the overheating of the wiring in the vehicle.
  • A bad alternator will make the battery dead and stop the electrical supply.

Suggestions for Extending the Life of Your Alternator

It is evident that if a person wants to increase the lifespan of any machinery. It is advised that the machine be adequately cared for. The same is the case with extending the alternator life expectancy. Similarly, by decreasing the load of an alternator, you can increase its lifespan.

• Replace the headlights with LED lights

Electrical power is required to run the headlights. The load reduction in the case of headlights can be achieved by replacing them with LED lights that require less energy to operate.

• Try to use the indicators that require less energy to operate

The indicators in automobiles require energy from alternators. It is advised to use the indicators that require less energy to operate. So that the expected life of a car alternator can be increased.

• Always use a battery of good quality

An automobile requires a battery to help it start. A battery of suitable quality requires less electricity to charge.

Proper monitoring is required for an alternator. Load reduction can result in high-efficiency work and, ultimately, extend the alternator’s lifespan.

How Do I Replace My Alternator?

Alternators in the car are placed in an accessible place so that everyone can see or change them. A belt at the front of the engine operates an alternator. Changing an alternator requires about an hour. The process of changing an alternator is different with different models of alternators.

Removing the previous Alternator

  • First, remove the negatives of the battery to cut the supply. This will avoid any hazardous situation.
  • Next, remove the belt of the Alternator.
  • Now, remove the connection of the Alternator itself so that plastic connectors won’t get damaged.
  • At the end, remove the belts used to hold the alternator.

Installing the new Alternator

It is advised that the Alternator you are replacing is of the same brand or company installed before. The cost of replacing your alternator can vary. Removing an old alternator is the exact opposite of installing a new one. After installing an alternator, start the car and check for the proper functioning of the installed Alternator.

It is not a job that could be done on your own. You can get some professional help for installing an alternator. To get high-efficiency tasks that an alternator performs, that would be without any doubt.

Is Your Problem with the Alternator or the Battery?

The most important question people usually ask about alternators is whether the problem is associated with the Alternator or the battery. A failing battery, a stalling engine, and jump starts are indicators of a bad alternator. The Alternator is a device that converts mechanical energy into electrical energy. This electrical energy is used to run different tasks in an automobile.

Suppose running the business is difficult, like starting a car engine or headlights. This means that the Alternator has gone wrong. The battery in the system is not getting enough charge to run the car’s engine. Similarly, a dead battery indicates that a car’s Alternator is not working.

The problem with the Alternator and the battery runs hand in hand. A bad alternator with a shorter lifespan will have issues functioning very easily, resulting in running out of battery easily. If there is a problem related to the electrical supply, there is something wrong with the Alternator and, in turn, with the battery.

Conclusion

A car has an alternator used to run different electrical tasks in the automobile. The Alternator is a device that uses mechanical energy to electrical energy. An alternator provides an AC supply that the rectifier converts into DC. The car alternator lifespan is a critical factor to consider when installing one. Many factors decide the life expectancy of alternators. Reducing the load of an alternator can increase the lifespan of the Alternator. It is straightforward to install a new alternator. Proper monitoring of the Alternator is required, which will pick up the signs associated with a bad alternator.
