Product Number: 12388N
The WAI 12388N is a brand-new 24V, 100A alternator. It is built to Bosch IR/EF specification, supplied as a direct replacement for Bosch, Delco Remy, Iskra, and Letrika original-equipment units across a wide range of agricultural and construction machines. With 103 OE cross-references catalogued, it is one of the most broadly referenced units in this voltage and output class, covering John Deere and Valtra Valmet applications including the John Deere 350D Series II, 400D Series II, and Valtra Valmet 540T.
Constructed to match the original design parameters, the 12388N features clockwise rotation and a groove pulley, ensuring a straightforward swap with no modifications required. The IR/EF (internal regulator, external fan) design is the standard architecture for heavy-duty 24-volt charging systems in agricultural and plant machinery, and WAI's brand-new build means there are no core returns, no exchange surcharges, and no risk of inheriting worn internals from a remanufactured unit.
