How Often Do Alternators Go Bad?

At the beginning of this article on car alternator cost, I told you I would be delving into other aspects of a car alternator. A common question when we talk about car alternators and the cost of car alternators is how often do alternators go bad?

Car alternators have a long life span and would not always need replacement. A good alternator will typically last as long as seven years or even longer. As per how often do alternators go bad, a car alternator may get damaged earlier than expected due to mechanical factors, wearing, and tearing.

Other factors that may cause a car alternator to go bad may include electrical overload and jumpstarting the car incorrectly. Furthermore, a car alternator may go bad due to leaking car fluids and tight alternator belts, leading to the crushing of an alternator’s bearings, causing permanent damage to the car alternator.

How to Know If Your Car Alternator Is Bad?

There is no part or component of a car that does not get bad. Sometimes, we are faced with unsuspecting mechanical breakdowns because we are not conscious of the warning signs the car gives. Of course, knowing when your car’s alternator is bad is essential, so you are not caught unaware when the car is about to break down.

To know if your car alternator is bad, the following are some of the signs to watch out for:

  1. Headlights become dimmer and could flicker from dim to bright momentarily
  2. The car’s electrical system begins to act abnormally
  3. The vehicle may be hard to start as a result of the lack of ignition power from the car alternator
  4. The warning light on the car dashboard illuminates
  5. Irregular rattling sound from the engine

How To Know If Your Car Alternator Is Still Working?

From the previous section, you will see a few tell-tale signs that can be used to ascertain if a car alternator is in bad condition. However, rather than wait to start seeing the symptoms of a bad alternator, you can check if your car alternator is still working.

A cost-effective way to check if your car alternator is still working is by using a voltmeter. You do this by attaching the voltmeter to the car alternator to read the charge it generates and see if it is generating the required voltage.

Also, you can test the battery using the voltmeter to check if the battery is charging and in perfect condition. Another way to detect if the car alternator is in proper condition is by starting the car and revving the engine to 2000 RPM. Doing this will draw power from the alternator to the battery and then kick the alternator into high gear.

When that is done, open your car bonnet and test the battery again to see if the battery is charging. If the battery is not charging correctly, it’s majorly because the car alternator is malfunctioning and therefore due for repair or replacement.

Can a Car With a Bad Alternator Still Move?

Driving a car with a bad alternator is not a good move in whatever regard. If you are driving a vehicle with a bad alternator, you are putting yourself and the car in bad shape.

A car with a bad alternator can move, but a vehicle in this condition may run for a short while before the engine gives way and it breaks down. In some cases, the car may not start when the alternator is bad as there won’t be the transmission of charges to the battery to ignite it.

To move further in this article on car alternator cost, let’s look at how long a battery can last without an alternator.

How Long Can a Car Battery Last Without an Alternator?

A car battery may not last for too long when the alternator is bad. A bad alternator gives little or no charge to the battery, and therefore without second-guessing, one is bound to have poor battery performance in such a car. Therefore, such a battery will not work.
