Built to restore charging performance on your excavator, this alternator assy cat 320c with s6kt engine 125-2994 delivers stable voltage output across the full RPM range. When OEM alternators fail, the electrical system suffers — ECU faults, sensor dropouts, and dead starts follow. This unit eliminates those issues with a direct-fit design that replaces the original without modifications.
