What Does an Alternator Do?
An alternator is a device found on all engine-powered vehicles that converts mechanical force into electricity. The serpentine belt drives the alternator pulley, rapidly turning a set of magnets inside a coil to generate an electrical field. The rectifier converts it to direct current (DC) that your car's systems can use and delivers it to the power distribution center. As well, power from the alternator is stored in the battery so your car will start.
Signs of a Faulty Alternator
You can usually count on the alternator for 2003 Ford F150 pickups to last for years. When it fails and a replacement is required, signs can consist of electrical systems slowing or stopping, a burning smell, rumbling or whining under the hood, a battery light on the cluster, and dim lights. If the alternator quits completely, the battery could be dead, or your car could stall out while you're at the wheel.
