This alternator is intended to replace OEM alternators in heavy trucks and large diesel engines. It supports remote sense functions, internal voltage regulation, and is compatible with engines such as Caterpillar (3116, 3126, 3176, 3306, 3406, 3408, etc.), Cummins ISB / ISC / ISL / ISM / ISX / N14 / Signature, Detroit Diesel, and many others.

Because electrical systems vary (battery capacity, wiring gauge, usage load), it is essential to verify fitment by mounting style, pulley size, plug/connector, and amperage demands before installation.
