TERREPOWER formerly BBB Industries N7798 alternator for the 2003 Ford E-350 Club Wagon 7.3L and other vehicles is a new alternator that charges the battery and supplies power to the electrical system while the engine runs.
A battery light on the dash, headlights that dim, or a battery that keeps going flat can mean the alternator is no longer charging. A tired battery or a loose belt can bring on these symptoms too, so they alone do not prove the alternator is at fault.
The 2003 Ford E-350 Club Wagon 7.3L, 1999-2003 Ford E-350 Super Duty 7.3L and 2003 Ford E-450 Super Duty 7.3L all take this alternator, one per vehicle, and it fits more trucks and vans besides. If your own vehicle isn't named here, look it up on the Buyer's Guide tab.
