Renault is one of the oldest car manufacturers and has a strong connection to motorsport, competing in over 300 F1 races. In 1977, the Renault RS01 became the first Formula One car to use a turbocharger at the British Grand Prix and earned the nickname ‘yellow teapot' due to overheating issues. However, the technology took off a few years later, and turbochargers became commonplace. One of Renault's most popular and iconic models is the Clio, which earned the title of ‘Best Small Car' at the CarBuyer Best Car Awards 2022.

The alternator plays a simple but crucial role in keeping your car's battery charged, which means it is also indirectly responsible for starting the vehicle and keeping various components running. It is like a small generator; the engine spins, and the alternator turns this movement into electricity.

Here are five signs your alternator is faulty.

Common reasons for car alternator repair include a failing voltage regulator (which ensures the battery receives the charge at the correct voltage) and worn brushes (which maintain electrical contact with the alternator). An alternator specialist can advise you on the cause of the problem and how best to fix it.

Rather than repairing the component, a total car alternator replacement may be required, which is a straightforward job that most mechanics can do. However, when considering an alternator repair vs replacement, the latter only occurs when multiple parts fail, and the repair cost would be close to that of fitting a new component.
