Product Number: 12090N
The WAI 12090N is a brand-new 12V 55A alternator. It is built to the Lucas IR/EF design specification, replacing original-equipment numbers from Ford, Lucas, Bosch, Delco Remy, Iskra / Letrika, Magneti Marelli, Mahle, and Remy across 30 cross-references. With 28 Ford and 25 New Holland Industrial vehicle applications on record — including the Ford 3230, 3930, 3430, 345C, 345D, 260C, 250C, and 445C — this unit is a proven direct-fit replacement for agricultural and plant machinery that left the factory with a Lucas IR/EF alternator.
Constructed to IR/EF (internal regulator, external fan) design principles, the 12090N delivers a 55-amp output at 12 volts with clockwise rotation and a groove pulley, matching the mechanical and electrical interface of the original unit. Being brand new rather than remanufactured means there are no worn brushes, degraded regulators, or fatigue-stressed components from a previous service life — the alternator leaves the box ready to perform at full rated output from the first start.
Ford OE references cross to this unit include E7NN-10B376-AB, E7NN10B376AB, and F0NN10B376BB; Lucas references include 24273, 24273A, and 54022336; and the Bosch USA equivalent is AL5050X. The full set of 30 cross-references spans Iskra / Letrika, Magneti Marelli, Mahle, Delco Remy, and Remy — making it straightforward to confirm a match from an old part label or workshop reference manual.
