The charging system converts mechanical energy into electrical energy to supply the current needed to recharge the battery and power the vehicle’s electrical accessories when the engine is running. The alternator, also called an AC generator, is where the electrical energy is created. Mechanical energy from the engine’s crankshaft is transferred by a belt from the crankshaft pulley to a pulley on the alternator, which is attached to the engine with brackets.

    Featured Brands

    A typical alternator has a two-piece cast aluminum housing enclosing a stator and a shaft-mounted rotor. The pulley and a cooling fan are mounted on the shaft at the front of the drive end housing, which also contains a bearing to support the shaft. In addition to another shaft support bearing, the rear housing also contains the brushes, rectifier assembly, and voltage regulator, if equipped. The rectifier assembly contains diodes and heat sinks.

    Electricity is produced when the belt spins the rotor inside the stator windings, creating a magnetic field that induces a voltage in the windings. Alternators produce AC current, which is rectified by the diodes and transformed into the DC current that recharges the battery and powers the electrical system. The voltage output of the alternator must be controlled to prevent undercharging or overcharging. This is done by varying the field current. On older vehicles this was done by an external or internal voltage regulator, but on most new vehicles regulator function is part of the Powertrain Control Module (PCM).

    We offer both brand new and remanufactured alternators from the most well-known and respected names in the automotive electrical parts industry. Every alternator meets or exceeds original equipment specifications for charging system performance. All are designed to be direct replacements, and will mount to your engine and connect to the electrical system in the same manner as your original alternator. Whether new or remanufactured, only premium quality components are used during assembly, and each alternator is thoroughly tested to ensure peak performance and long term durability.

    In addition to alternators, we also offer replacement pulleys. During deceleration, the spinning alternator creates drag, straining the serpentine belt and tensioner. Some manufacturers use alternator decoupler pulleys, which allow the alternator to freewheel during deceleration, eliminating strain and increasing belt and tensioner lifespan. There are One-Way Clutch (OWC) and Overrunning Alternator Decoupler (OAD) pulleys. Both function similarly, but the OAD also contains a mechanism to reduce vibration. Many OE dealers do not service these pulleys separately from the alternator, but we have them, so you can save money.

      Starter motors and alternators have a tough job. Starter motors are high-torque motors which must have the ability to turn over, or crank, an engine under varying weather and mechanical conditions. Without a functioning starter motor, you simply cannot start up a modern vehicle's engine.
