A generator is used to ensure that the systems all function smoothly, including the alternator called, electric current is generated when the engine is running. The alternator also charges with the engine running the starter battery. This ensures that enough energy is available for the next start-up. There is also a corresponding light for the indicator lights in the dashboard charge control installed. This lamp lights up too after starting the engine further, this indicates a problem with the generator. And that can have fatal consequences. Because in such a case the power supply takes place exclusively from the battery.
Find a glowing battery light!

A lighting of the charging indicator light, also known as the battery light, can have various causes. The charging indicator light stands out.

But also the fuel pump and many other components (for example the windshield wipers) no longer work correctly. And this can lead to dangerous situations for oneself, however also for other road users come.

Without power from the generator, energy is only drawn from the battery, which can lead to sudden engine failure.
