Product Number: 12728N
The WAI 12728N is a brand-new 12V 50A alternator. It is built to the Mitsubishi IR/IF specification, replacing original-equipment units referenced under Mitsubishi A007TA1491 and A7TA1491, as well as Delco Remy DRA0257 and seven further cross-referenced part numbers. It is designed to restore charging performance on Lister-Petter and Hawkpower machinery — including the Lister-Petter LPWG4, LPWS4, and the Hawkpower GS12D-LP — covering 10 OE applications in total.
As an internally regulated, internally fused (IR/IF) unit, the 12728N requires no external regulator, simplifying installation on compact industrial and generator sets. Clockwise rotation and a groove pulley are built in as standard, matching the drive configuration of the applications it serves. At 50 amperes output, it provides a reliable charge margin for the electrical demands of the supported engine families.
With WAI's engineering backing and a brand-new build condition, this alternator offers a dependable direct swap rather than a reconditioned compromise. The groove pulley is fitted ready to use; confirm belt type against your application before ordering.
