Frequently asked questions about Mercedes-Benz alternator repair & replacements

Read our answers to questions about alternator repair costs, symptoms and more.

What does an alternator replacement on my Mercedes-Benz involve?

  • Mechanic will inspect the car's battery charging system.
  • Mechanic will inspect the alternator's ancillaries (drive belt, cables etc.)
  • Mechanic will test the voltage output of the alternator.
  • If necessary, the mechanic will replace the alternator.
  • Mechanic will advise if any other parts of the electric system need to be replaced.
  • Mechanic will test the charging system and will test drive the car.

What are the symptoms of a bad Mercedes-Benz alternator?

  • When the battery warning light on the car's dashboard has lit up.
  • When the battery is not being recharged

How long does it take a mechanic to replace an alternator on my Mercedes-Benz?

On average, alternator replacement times can range from 1 hour to 2.5 hours with an average of just over 1 hour. The time that the job takes will depend on a number of factors, like your vehicle's make and model, year, as well as other factors. Select your car at the top of this page for information on job time and cost for your vehicle through ClickMechanic.

How often should I replace an alternator on my Mercedes-Benz?

Generally alternators only need to be replaced if there is an issue with them. Should you experience any problems like those listed it is important to have the battery charging system inspected and, if necessary, have the alternator replaced.

As the demand for more and more electrical equipment and devices on modern vehicles increases, the demand on the alternator is increased. Therefore whilst the units themselves have improved dramatically in design and reliability, this is outweighed by the increased reliance on it. So, alternator replacement is a frequent repair on most vehicles at some point.

What are the signs of a bad Mercedes-Benz alternator?

If the battery light remains on with the ignition (and does not go out once the charging is in operation), or comes on with the engine running then there is an issue with the alternator generating power and the battery will not be recharged. It is important to get a professional mechanic to check the issue as soon as possible.

How can I extend the lifetime of my Mercedes-Benz alternator?

Because it is not possible to turn the alternator off and it will therefore always be turning when the engine is running, there is little you can do to prevent wear and tear. Obviously as an electrical device, they do not like water, so avoiding flooding is important!

Can a bad or faulty alternator affect a new battery on my Mercedes-Benz?

A bad alternator can damage a new battery if the battery is not receiving the proper charging voltage. While it may not completely destroy it, a faulty alternator can cause a new battery to drain more quickly than it should.

Can an alternator on my Mercedes-Benz fail suddenly?

Alternators can fail suddenly, but more often than not they will slowly lose their ability to charge the battery and eventually die. So even if it fails while driving, you may still be able to drive the car a few miles before the car comes to a complete stop.

How do I check if my Mercedes-Benz alternator is working properly?

The easiest way to check if your alternator is working is to start the car and let it idle. Then, turn on all of the car's accessories one at a time. If the car's battery dies while the accessories are on, then the alternator is not working.

Additionally, the battery should be tested for voltage. If the battery is low, the alternator may not be charging the battery. Depending on the electrical system, a voltmeter reading in the 13.8 to 15.3 volt range with the engine running, lights and accessories off, generally indicates that the alternator is working as it should be.

Can I jumpstart my Mercedes-Benz with a bad or faulty alternator?

If the battery is not dead, then yes, you can jumpstart a car with a bad alternator, but it will only run for a short period of time before the battery is drained again.

What happens when the car alternator fails while I am driving on my Mercedes-Benz?

If your alternator dies while driving, your car will eventually lose power and come to a stop. You may notice the first signs of a dying alternator with dimmed interior lights and warning lights on the dashboard. The best thing to do in this case is find a safe place to stop and call for professional help.

How do I fix a bad Mercedes-Benz alternator?

In most cases the alternator would be replaced if it bad or faulty. Alternators can be refurbished but often getting a new one fitted is more cost-effective. An alternator is an electrical component that is key to supplying power to your car so fixing it is a job best left to qualified technicians.
