ALTERNATOR

This is a heavy-duty 12-volt, 160-amp alternator designed for commercial trucks and buses. It uses a pad mount style, which bolts directly to a flat surface on the engine, instead of a traditional bracket. A common reason to replace this unit is when the vehicle's batteries aren't being charged properly, often signaled by battery warning lights or a no-start condition, due to worn brushes, failed diodes, or a bad voltage regulator.
