Alternators, Starters & Components for heavy-duty vehicles

Alternators, starters, and their related components should be always maintained in every truck. They are key components of a vehicle’s electrical system and play a critical role in generating and managing electrical power for various vehicle functions, like starting the engine and charging the battery.

What is the alternator?

The alternator is a generator that converts mechanical energy from the engine into electrical energy to power the vehicle’s electrical components and recharge the battery. It is driven by a belt connected to the engine and consists of a rotor, diodes, voltage regulator, as well as other components. The alternator provides a continuous supply of electricity to the vehicle when the engine is running, making sure that the battery remains charged and the electrical systems can function properly.

What is the starter?

The starter is an electric motor that initiates the engine’s combustion by cranking the engine when you turn the ignition key or push the start button. The starter motor draws power from the battery and engages a gear called the pinion with the engine’s flywheel, turning the engine over until it starts. Once the engine is running, the starter disengages, and the alternator takes over the task of supplying power to the vehicle.

Both the alternator and the starter are made up of a wide range of components, including voltage regulators, solenoids, brushes, bearings, pulleys, belts, and more. These components are crucial for the proper functioning of the alternator and starter, as well as the entire engine.
