A direct-fit replacement 12V 90A alternator for John Deere tractor applications. The alternator generates AC electricity as the engine runs, which is converted to DC power to charge the battery and supply the vehicle's electrical system. A failing alternator typically presents as a flat battery that will not hold charge, dimming lights under load, or complete electrical failure even with a known good battery.

Manufactured to OEM specification with internal regulator, internal fan, clockwise rotation, and 8-groove pulley with 49mm outer diameter, cross-referencing John Deere OEM part number AL114092 for straightforward identification. Note: the original unit was fitted with a decoupler pulley - this replacement is supplied without pulley. This unit features a W-terminal and is not interchangeable with ABO0429 which does not have this terminal. Verify your model and year against the fitment table before ordering.
