The alternator is the main power source for the diesel engine during normal operation, it supplies power to the electricity-using equipment and charges the battery. The diesel alternator is mounted on the cylinder block of the engine. When the diesel engine is working, the rotor of the diesel alternator is rotated by the belt, and the belt tightness can be adjusted by the adjustment lever.

What Is an Aftermarket Alternator?

A diesel engine alternator is an important component of a charging system, responsible for converting mechanical energy into electrical energy to power the equipment's electrical system and charge the battery. The parts of an alternator include brushes, pulleys, fans, rotors, stators, rectifiers, voltage regulators, etc.
An aftermarket alternator is a replacement part that is not manufactured by the vehicle's original equipment manufacturer. MyMROmarts aftermarket alternators are designed to match the original part's specifications, providing your equipment with better durability and higher power output.

How Does an Alternator Work?

The working principle of an alternator is to convert the energy generated by diesel combustion into mechanical energy through an internal combustion engine. The mechanical energy is then converted into electrical energy through a generator.
As long as you have DIY ability, when the engine fails, you can also consider replacing it yourself. Understanding the working principle of alternator can help you replace the broken electric alternator.
