OEM GM Alternators Online

The alternator of your vehicle plays the important role of keeping your car battery charged while you drive. It does this with the help and momentum of the serpentine belt.

How an Alternator Motor Works to Power Your Vehicle

The alternator is a motor with a rotor that spins from the motion of your serpentine belt, which runs off a system of engine pullies. The belt spins the rotor which spins a pair of electromagnets around a coil at a rapid rate creating voltage. This power is distributed to charge the car battery. In most cases, it also powers other features like your electric windows or wiper blades.

Signs of Alternator Failure

When starting your vehicle, if you notice a whining or whirring noise, notice electric short circuits or dimming lights, experience a dead battery, or an unhealthy ignition start, it made be because your alternator has begun to fail. This will eventually lead to a dead battery leaving stranded. If you notice these signs, seek an inspection and repairs ASAP.
