TERREPOWER formerly BBB Industries 8231-5 alternator for the 2000 Chevrolet Astro 4.3L and other vehicles is a remanufactured unit that turns engine rotation into electrical power for the battery and the rest of the electrical system.
A battery warning light, dim headlights or a battery that keeps going flat can mean the alternator is worn, though a weak battery or a slipping serpentine belt can be behind them too, so find the cause before you replace it.
The vehicles it fits include the 1998-2000 Chevrolet Blazer 4.3L and the 1998-2000 Chevrolet S10 4.3L, with one alternator per vehicle.
