Electrical device used to generate electicity in plant vehicles. The device gets energy via a drive belt from the engine, and converts this mechanical energy into electrical energy to be used by the vehicle electrical systems. Once the engine is running, the alternator supplies all electrical loads in a plant vehicle.

The three things necessary to generate electicity.

Alternator, with part of the stator cut away and folded out to facilitate viewing the rotor.

As the name implies, the unit produces alternating current, which cannot be used by plant vehicles. This output must be rectified to direct current by using diodes.
