The Bosch Premium Alternator delivers exceptional performance and reliability, making it a trusted choice for your vehicle’s electrical system. With a 55-amp output and 12 VDC voltage, this alternator is full-load tested to meet Bosch’s rigorous performance standards. Unlike rebuilt units, it is 100% factory-tested and remanufactured using high-quality materials and cutting-edge technology, ensuring long-lasting durability. Designed for clockwise rotation, it is engineered to handle demanding conditions while maintaining consistent power delivery. Whether you’re replacing a worn-out alternator or upgrading for better performance, this Bosch unit offers unmatched value and dependability.

This 100% NEW alternator from WAI is a premium choice for those seeking reliability and performance. Engineered to meet or exceed OEM specifications, it ensures a perfect fit and hassle-free installation. Its advanced voltage regulator protection guards against transient voltage spikes, preventing potential battery damage, while the low saturation voltage minimizes heat dissipation for enhanced durability. The high-power rectifier assembly, featuring open junction press-fit diodes, is designed to keep the unit running cool even under demanding conditions. Fully compliant with ECU communication, this alternator guarantees seamless integration with your vehicle’s system. Each unit comes with a printed copy of test results, providing transparency and confidence in its performance from the very first use. Built for long-lasting efficiency, this alternator delivers exceptional value for your vehicle’s electrical system.

The charging system has been required as long as we have had a need for an electrical system and from research it’s been since the requirement of horns in motor vehicle in the early 1900’s. An alternator is a voltage generator that uses mechanical energy to rotate a set of magnets within a field of windings called a stator. The alternating current (AC) voltage created by the spinning magnetic field is converted into a usable direct current (DC) voltage with a rectifier and then regulated by a voltage regulator so that the voltage level in the electrical system stays within a specific operating range. The alternator provides all the voltage needed to operate a vehicle, the battery is only used as a reserve for heavier load conditions, as a voltage source for the engine starting system, and to supply a small amount of voltage to the electromagnets in the alternator which boosts the magnetic field in the alternator and increases voltage output.
