What does an alternator do?

The alternator is the device responsible for generating electricity to charge the battery. It’s coupled with the engine drive, which means whenever the car is running, the battery is being charged. Without a charged battery there is no delivery of power to the electrical components or to generate the sparks used to combust the fuel in the engine.

How often should an alternator need replacing?

An alternator typically lasts around 7 years or between 100k and 150k miles.

The law, vehicle regulations and your MOT

Without a correctly functioning alternator, your car is unlikely to hold enough charge in the battery to drive for any purposeful length of time. Having said that, the alternator won’t be tested during an MOT, so as long as the battery has enough charge for the engine and other electrical components to run for the duration of the examination, then it can still achieve a pass. We do not recommend this in any circumstance. If there is a problem with your alternator, you should have it repaired or replaced as soon as possible.

What happens when we replace your alternator?

  • Our efficient and fully qualified mechanics will test the voltage output of the alternator, inspect the car’s electrical systems and all alternator ancillaries (drive belts, cables, etc.).
  • Wherever necessary, the alternator will be replaced, and you will be advised of any other connected or associated problems arising from its malfunction.
  • You will also be advised of any other parts that may need to be replaced for the best operation and health of your vehicle.
  • Once the faulty alternator has been replaced, our mechanics will test it thoroughly to ensure the correct running of the new part and make any adjustments required for its premium operation.

What causes an alternator to stop working correctly?

An alternator might break down due to a bearing failure, preventing the rotor from spinning freely. Fluid leaks or a too tight belt (or a loose belt slipping) can also cause damage and premature wearing.

Symptoms of a malfunctioning alternator

When the battery is flat

If your battery is flat and refuses to accept charge through normal driving, then your alternator could be the problem.

The lights aren’t as bright as normal

If your headlamps aren’t as bright as normal or the function of other electrical components is weak, your alternator may not be supplying as much charge to the battery as it needs.

The battery warning light is illuminated on the dashboard

All warning lights are an indicator that a sensor has detected a failed component or poor operation. A battery warning light could be connected to your alternator performance.

Mercedes-Benz

Mercedes-Benz is a German global car manufacturer and a division of Daimler AG. They were established over 100 years ago in 1926 and have grown to be the biggest selling premium vehicle brand in the world.

How popular is Mercedes in the United Kingdom?

The number of Mercedes cars on the road in the UK continues to rise, reaching 1.9million by the final quarter of 2018. There are almost 5 times as many Mercedes cars on the road as there were in 1995, showing just how popular this marque has grown to be.

Helping these powerful statistics on their way, the Mercedes A-Class was announced as the 8th best selling car in the UK in 2018. The premium family hatchback is vying for position against the ever-popular VW Golf—the current leader in this class.

Premium executive models of every shape and size

Mercedes deliver hatchbacks, saloons, estates and coupés at every size from their A- to E-Class ranges, as well as executive SUVs, the V-Class MPV, and of course, a more than desirable selection of convertibles and roadsters.

With prices rising to well over £100k, Mercedes cars are a great contender as the executive car of choice.

Mercedes-Benz: Giants of Formula One

Mercedes has always been a keen player within the F1 championship, taking their first 2 titles back in 1954 and 1955. Through the 1990s they joined forces with McLaren as an engine provider and part owner, bringing titles for both Mika Häkkinen and Lewis Hamilton and a constructors championship in 1988.

Their current and outright domination of the sport began in 2014, as a team in their own right, it has featured 5 straight constructors titles, with Lewis Hamilton taking 4 world championships and Nico Rosberg taking the other in 2016.

Mercedes’s reliability and reputation

Mercedes ranked 26th place out of 30 car brands in the What Car? Reliability Survey in 2018 with an efficiency rating of 88%. You could be forgiven for expecting German efficiency to rank higher through the marques, however, most of the top 10 places were occupied by Japanese and Asian manufacturers.
