How your car’s alternator works

The alternator, which is located on the engine, provides power to the battery and continuously charges the battery and the car’s electrical systems and computers. (Honda Accord Alternator Replacement)

Alternator typically lasts about seven years, or about 100,000 to 150,000 miles, adds Waits. Some mechanics, though, say they typically see alternators last about 80,000 miles. Several factors can affect how long an alternator lasts, including the quality of the part, conditions in which the car is driven and how many electronics are being used inside the car.

The alternator is located in the rear of the engine.

In some cases, when an alternator is about to die, there are a few warning signs. Identifying what those signs are can signal you to have it checked by a mechanic, which can save you from being stranded on the road.

  • One of the most common signs of a faltering alternator is when the headlights start pulsating at night, from dim to bright.
  • Some alternators may stop working if they are charging several electronics at once.
  • Other signs may include an electrical burning smell coming from the alternator, or the battery, the alternator warning light or other dashboard warning lights turning on.
  • A struggling alternator may also cause your car radio or other electrical components to work intermittently, or cause a squealing noise in your car’s engine.

Maintaining your alternator

There are some maintenance techniques that can prevent premature wear of your alternator. Many Honda Accord owners take actions that can cause the alternator to fail, such as starting the car in the opposite direction of the current, or installing accessories that overload the car.

Additionally, fluid leaks into the alternator or a belt that is too tight can also damage the alternator bearings, causing them to wear prematurely. If the alternator stops working properly, the car’s electronics can begin to drain all the power from the battery, which can cause it to discharge completely. For this reason, in many cases the alternator is the main problem, instead of the battery.

Below we will give you a short list with simple steps that you can take to properly maintain the alternator of your Honda Accord 2018-2020. 

  • Regularly inspect the alternator’s electrical connections for signs of corrosion or damage to the cables.
  • Check that the engine fluid level is correct and make sure there are no leaks in the alternator.
  • Check the tension of the alternator belt and adjust it if necessary.
  • Limit excessive use of electrical accessories, as this can overload the alternator.
  • Follow the maintenance schedule recommended by the vehicle manufacturer or your trusted mechanical engineer to ensure the alternator is in good condition.

By following these simple steps, you will not only extend the life of your alternator, but you will also ensure safe and reliable operation of your Honda.
