About Subaru Legacy Alternator

The alternator is driven by belts in the engine, where it produces an alternating current, which is converted internally to 12 volts direct current by the diode bridge or rectifiers. Diagnosing your Subaru Legacy alternator can be tricky because when this part fails it can present a whole host of different symptoms. In addition, a failing Subaru alternator will fail gradually until all electrical accessories in your car will not work and your car finally dies. Fortunately, we offer a great selection of new and remanufactured Legacy alternator products, including high-output replacements for you electronics junkies.
