Vehicle Alternators Explained

A vehicle's alternator acts as a miniature power generator. Each time a vehicle runs, the alternator creates the energy needed for the electrical components of the vehicle and charges the battery. A running engine turns a wheel on the alternator, which enables the part to create electricity. The battery merely contains the energy needed to start the vehicle.

When vehicle owners notice that the headlights are dimmed, alternator problems are the likely reason. Drivers might also smell the burning rubber on the alternator belt or notice an unusual screeching or whining from a loose or defective belt. While often times an expired battery prevents you from starting the vehicle, the alternator may also be the problem. Check the alternator belt along with the battery terminals and cables in the event that the vehicle does not start. When vehicle problems arise, schedule an inspection with one of our technician at DeMontrond Volvo Cars.
