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.

Founded by a Scottish marine engineer in (you guessed it) Vauxhall, London in 1857, the company has been under the umbrella
of American giant General Motors since 1925. Notable former Vauxhall cars include classics such as the Victor, Chevette,
and Cavalier, while the current car range includes city cars like the Adam and Viva, extended range electric cars like the
Ampera, the Astra, and the Zafira Tourer, a large MPV. Vauxhall also sells high-performance versions of a smattering of its
offerings under the sub-brand VXR.
In the UK market at least, Vauxhall is regularly in the running with Ford to top the sales charts (although it’s never
quite taken top spot).
About the Vauxhall Corsa
Due to generous offers on the sales front, the previous model of the Vauxhall Corsa was one of the most popular sold in
the UK after its introduction, despite similar offerings from the other big producers. However, the current Corsa makes
a number of improvements on its predecessor including loads of extra space and improved looks. With three and five door
options, there’s something for everyone. The main issue that has come up with this make, particularly the 2008 Vauxhall
Corsa, is clutch burnout. If that’s been a problem for you, we can help you find the right garage to fix the problem.
