Auto Electrical Parts
The purpose of a car alternator is twofold: first, it supplies the battery with its electrical charge. Secondly, while the engine is running, the alternator powers the car's electrical system, easing the burden on the battery to ensure the battery has enough juice to continue to provide electricity when the ignition is turned off. Equipped with pulleys, car alternators can revolve twice as fast as the engine itself, allowing them to generate a great deal of electricity when the motor is running idle. Operation of Car AlternatorsIn newer cars, the alternator is usually linked with the in-vehicle computer via an electronic interface and features an adjustable battery charging voltage. The efficiency of this piece of equipment can be limited by a wide variety of factors (such as fan cooling loss); thus, one of the key reasons alternators fail is due to a deficiency in various other auto parts. This causes it to work harder to produce the same amount of energy, eventually leading to burnout. Most passenger vehicle alternators run at about 70 amps, though models that produce as much as 300 amps are not uncommon in larger vehicles like coach buses and tractor trailers.
