The remanufactured TERREPOWER 7773 alternator for the 2002-2004 Ford Explorer 4.6L and other vehicles charges the battery and supplies power to the electrical system while the engine runs.
A dim or flickering light, a battery warning light or a battery that keeps going flat can mean the alternator is failing. Before you replace the alternator, rule out a weak battery, corroded cable ends and a slipping belt, which can leave you with the same lights.
The 2002-2004 Ford Explorer 4.6L, 2003-2005 Lincoln Aviator 4.6L and 2002-2004 Mercury Mountaineer 4.6L each take one of these alternators and are among the many vehicles it fits. Open the Buyer's Guide tab to check your exact model and engine.
