What is a car alternator?

A car alternator keeps your car's battery charged, which is obviously important because a charged battery starts your car and powers everything electrical within it. It does so using a drive belt (sometimes referred to as a serpentine belt) to convert the mechanical energy of the car's rotating crankshaft into electricity through a process of induction.

What are the possible signs of a faulty alternator?

  • Your car is difficult or slow to start.
  • Growling, whirring, whining or squealing noises are emanating from your car's engine.
  • Your car’s interior and exterior lights seem too dim, blink erratically, gradually fade, suddenly get brighter or don’t come on at all.
  • The red light on your car’s dash with the image of a battery (or the words ALT or GEN) becomes illuminated.
  • Your speedometer has stopped working.
  • You can smell rubber burning.
  • Your car fails a multimeter test at a garage.

What is the cause of a faulty car alternator?

  • The component, a brush, which maintains constant electrical contact with the spinning alternator, becomes worn.
  • The voltage regulator, which makes sure that the electrical charge is passed to the battery at the correct voltage, fails.

How long does a car alternator last?

  • On average, a car alternator can last for 8-12 years without needing for any repairs.

How much does it cost to repair a faulty alternator?

  • On average, it costs between £150-£300 to repair or replace a broken car alternator depending on the vehicle.
  • Refurbished car alternators are available but do not offer that much of a cost saving.

About Renault

Another French company churning out good-looking vehicles, Renault has been in the business of making cars since 1899. The alliance of Renault with Nissan (conveniently called the Renault-Nissan Alliance) make up the fourth largest automotive group in the world.

Renault is also widely known for its role in motor sport, particularly Formula 1. Early work on mathematical curve modelling used on Renault car bodies is an important, but little known, part of the history of computer graphics. Renault began to take part in motorsport early in the 20th century, largely due to Marcel Renault’s own interest in the sport. Over the years, Renault acquired multiple companies with sporting connections, and in the 1970s set up its own dedicated motorsport division, Renault Sport, winning both the Le Mans 24 Hours race and the Renault Alpine A442.

But back to the world outside of motor sport! Back in 2013, the newest Renault vehicles had the lowest average CO2 emissions among European generalist brands, average at 110.1g/km.
