Product Number: 10944N
The WAI 10944N is a brand-new 12V 35A alternator. It is built to the Kokusan Denki ER/EF design specification, replacing John Deere original-equipment references AM877957 and AM880339, as well as Kokusan Denki reference GP9178. It is a direct-fit replacement for applications that originally carried Kokusan-manufactured charging equipment, delivering reliable electrical output where the original unit has worn or failed.
Constructed to OE specification, the 10944N features clockwise rotation and a groove pulley configuration, ensuring correct belt alignment and drive engagement on compatible installations. As a brand-new unit — not reconditioned or exchange — it requires no core return and arrives ready to fit straight from the box.
The 35A output rating makes this alternator well suited to compact agricultural and plant machinery that demands dependable low-load charging performance. Cross-referencing against John Deere part numbers AM877957 and AM880339 confirms suitability for the original Kokusan Denki ER/EF platform; buyers should verify their existing part number or consult the selection widget before ordering.
