One New Aftermarket Replacement Rectifier Assembly for Caterpillar (Cat) Equipment
This rectifier assembly (also identified as Rectifier AS-Alternator) is an internal component of the alternator charging system on a wide range of Caterpillar (Cat) construction, earthmoving, pipelaying, and track-type equipment. The rectifier converts AC current generated by the alternator into DC current to charge the battery and power onboard electrical systems. Replacing a failed rectifier restores proper alternator output without requiring a full alternator replacement.
