Just because your batter seems dead doesn’t mean it’s actually dead. It may simply not have been charging. There are several reasons for this, most of them minor and easily corrected. A loose or corroded battery cable is the usual cause. A loose fan belt can also contribute to a failure of the charging system. If neither of these seem to be the cause and your battery is still new, or checks out as functional, the problem lies in the alternator. When you come right down to it, the battery’s only real purpose is to start the vehicle, or keep electrical components going when the engine is turned off. Under normal circumstances, the alternator does all the work of providing electrical current to the vehicle systems. Ultimately, any alternator will wear out – typically, after about 75,000 miles or so. When your old alternator has passed on, replace it with a Mean Green Alternator that provides up to three times more charging power. The Mean Green Alternator is built to last, with heavy duty sealed bearings at both ends and solid copper starter windings, sealed with high temperature insulation.
