A few glaring issues are where it all begins: A momentary dash light, perhaps dimmed headlights, and a few flashing instruments. Maybe there’s even a strange odor coming from beneath the hood, or there’s a growling noise. Is this an instance of car possession? No. It’s most likely one of several potential alternator issues, and if it isn’t fixed quickly, it might result in everything from a car that won’t start to a dead one. Even though an alternator only has a few components and is a very simple component, it is essential to the running of any vehicle. Through induction, it converts the mechanical energy of the engine’s revolving crank shaft into electrical energy. Throughout the alternator, wires cut through a magnetic field.
