Alternator

Alternators are essential components of a vehicle's power supply system, responsible for generating electrical energy to power onboard systems and recharge the battery while the engine is running. Typically engine-mounted and driven by the crankshaft via a belt, alternators convert mechanical energy into alternating current (AC) which is then rectified to direct current (DC) for use in the vehicle. These parts are critical for vehicles ranging from passenger cars to commercial trucks and vans. Key characteristics include amperage output, voltage regulation, and pulley design, all influencing charging efficiency and system reliability. Examples within our Electrical & Lighting > Power Supply > Alternator category include units from Bosch (MPN F00M346097), Febi (MPN FEBI17202 and FEBI33871) and direct fit units for Audi and MAN (MPN 51.26101-7314).
