Product Number: 10931N
The WAI 10931N is a brand-new 12V 20A alternator. It is built to the Kokusan Denki IR specification, cross-referenced directly against Isuzu original-equipment numbers 8972268403 and 8981565270. It is a direct-replacement unit for plant and agricultural machinery originally fitted with Kokusan-manufactured alternators, making it a reliable sourcing solution when the OE part is discontinued or unavailable through the main dealer network.
Constructed to match the original internal-regulator design, the 10931N delivers a 20-amp output at 12 volts — consistent with the electrical demands of the light-duty charging systems found on Isuzu-engined equipment. The groove-pulley configuration ensures compatibility with standard multi-ribbed or V-belt drive arrangements as fitted to the original application.
The unit also cross-references against KOKUSANDEN numbers GP9906 and GP9926, as well as the AD Kuhner reference 554348RI, giving workshops and buyers multiple routes to confirm the correct application before ordering. Five cross-references are registered in total across the Isuzu, Kokusanden and AD Kuhner ranges.
