How your car’s alternator works

One of the most common signs of a faltering alternator is when the headlights start pulsating at night, from dim to bright.

Some alternators may stop working if they are charging several electronics at once.

Other signs may include an electrical burning smell coming from the alternator, or the battery, the alternator warning light or other dashboard warning lights turning on.

A struggling alternator may also cause your car radio or other electrical components to work intermittently, or cause a squealing noise in your car’s engine.
