If you are unsure about what an alternator does for your vehicle, just know this: it is the device that generates electrical energy in your vehicle. After the engine starts, the engine turns the alternator’s belt-driven pulley. This is what provides your vehicle with the electronic energy it needs.
The alternator also sends energy back to the battery, keeping it fully charged. The battery needs to remain fully charged so that your car can pull on the reserve of energy when it has increased electrical demands. An example of an increased electrical demand is when your vehicle’s lights, wipers, defroster, and radio are all working at once and on high power.
Your vehicle’s alternator is what helps supply electrical energy to your car, truck, SUV or crossover. This vital component of your vehicle’s performance sends energy to your battery. It keeps the battery fully charged and ready to be used during increased electrical demands, for example having your heat, radio, and wipers on at the same time.
Your vehicle’s lights may dim, or accessories that require electrical energy may slow down. For example, if your power windows are moving slowly.
The light on your dashboard will illuminate. Depending on the year and make of your vehicle, the light may be an “ALT”, “GEN”, or shaped like a battery. Refer to your vehicle’s owner manual for the alternator icon on your vehicle.
Your battery is dead. Although a dead battery isn’t always a sure sign that your alternator is failing, it could be a sign that you’re having alternator problems if the battery is fairly new, or you know that the battery is in good working condition.
