Product Number: 12750N
The WAI 12750N is a brand-new 12V 65A alternator. It is built to Lucas IR/EF design specification, replacing original-equipment Lucas references including 61920357, LEA0270 and NAB900, as well as Prestolite Electric and other OE numbers across a total of 10 cross-references. It is a direct aftermarket replacement for applications originally fitted with this Lucas IR/EF charging unit.
Constructed to match the original IR (internally regulated) and EF (externally fan-cooled) architecture, the 12750N delivers a 65-amp output at 12 volts — the same rating as the OE unit it replaces. The groove pulley configuration is retained from the original design, ensuring compatibility with the correct belt profile on the host machine without modification.
Being brand new rather than remanufactured, the unit requires no core return and arrives ready to fit straight from the box.
