Mower & Small Engine Voltage Regulators

Shop aftermarket voltage regulators and regulator rectifiers for riding mowers, lawn tractors, zero-turn mowers and small-engine equipment. Find replacements for listed John Deere, Kohler, Kawasaki and Onan part-number paths, plus selected utility-vehicle applications.

Start with the original regulator number, then match the connector, terminal functions, mounting pattern and charging-system rating. Engine model, specification code and equipment serial number help distinguish electrical configurations that share a model name.

Choose an individual regulator or a listed stator-and-regulator kit. Each kit identifies its included components and links to the matching regulator when available separately. Open the product fitment section for model references and application notes.

Fitment support before and after purchase.
