What Does Your Car Alternator Actually Do?

Your car alternator is the generator that supplies energy to your car battery and electrics when your car is in motion. As you drive through Southampton, your car transforms mechanical energy into electricity to power your windshields, headlights, other electrics and to keep your battery juiced. Considering how closely the alternator and the battery work, it's helpful to know how to properly troubleshoot the former.

Battery Vs. Alternator

Your car battery gets your car started, but your alternator keeps it going. One way to tell which one is in trouble is: remove the jumper cables after jump starting the dead car. If the car dies again, your alternator is probably to blame. If the car keeps going, your battery is probably causing the trouble.

Tips on Spotting a Failing Alternator

Since your alternator powers your car's electrics, failing electrical components are typically the sign of a failing alternator. Poorly functioning headlights and windshield wipers, for example, are telltale signs of a dying alternator.
