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.

Japanese firm Subaru’s heritage comes from the skies: the company developed out of the Nakajima Aircraft Company (1917-1945), which in its day was the largest aircraft manufacturer in Asia. In 1954 the company debuted its first automobile with the Subaru 500, Japan’s first mini, but Subaru’s story really started in 1972 with the launch of its symmetrical all wheel drive. It’s this factor above all which makes Subaru stand out from the crowd - 4x4 is standard on every car that Subaru sells in the UK (apart from the Justy city car).
Subaru currently sells seven models into the UK including the popular Outback, the original ‘crossover’ and a trusty and tough SUV. Other much loved models include the Forester, a slightly smaller SUV ideally suited to rural driving, and the Impreza - a rally champion turned practical family car.
Subaru owners display impressive brand loyalty, and for good reason. These cars are known for their longevity - it’s not unusual to see Foresters and Outbacks on the used car sales boards with over 200,000 miles on the clock. Part of the reason for this is Subaru’s unique flat-lying ‘boxer’ engines, with pistons which punch horizontally, like a boxer, rather than up and down as in a traditional engine. This means less vibration and friction, and better lubrication, particularly on start-up. In some ways, Subaru build cars which are seemingly almost indestructible! For safety and reliability across the board they consistently score very highly indeed with drivers and independent reviewers.
