First Call GB Ltd - The alternator is the component in your car responsible for converting mechanical energy into electrical energy whilst you are driving. This is vital to charge your car battery, and problems with the alternator are another common cause for flat batteries. It is difficult to prevent problems with your alternator, so the best thing you can do is be aware of the warning signs that something may be about to go wrong. Look out for slower electrical functions and dimmer lights, and pay particular attention to an intermittently flashing battery warning light on your dashboard.
