The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.
This alternator from Bosch is exactly what you need to get your starting and charging system functioning properly. With the proper amperage, mounting locations, and wiring connections, this brand new unit will keep your battery charged and your electronics and ignition system in good shape. The perfect alternative to expensive dealership parts.
Want to check to see if your alternator is operation properly? Take a multimeter and test the battery voltage while running. The battery should be charging at about 14.5 volts. If you are watching voltage slowly drop, or if it is not charging at that voltage, it's time for a replacement.
This is a remanufactured alternator that includes a $80.00 refundable core charge.
