This aftermarket starter solenoid serves as a compatible replacement for the ATV Yamaha PRO HAULER PRO-4 YFU1 1989. It precisely matches the factory OEM part numbers 59V-81940-00-00 and 3GD-81940-00-00.

This functional component transfers 12V power from the vehicle battery over to the starter unit. It helps deliver steady engine turnover for quick and reliable ignition every single time.

Built with a heavy-duty sealed outer structure, it adapts perfectly to rough off-road surroundings. It works well to fix typical starting faults like sporadic cranking, repetitive clicking sounds and unresponsive startup issues.
