Good To Know

Q: How do I know my solenoid has failed? A: A common sign is a single loud click with no engine crank when you press start, along with battery voltage that stays strong. Testing the small trigger wire for voltage while cranking helps confirm the solenoid is the fault.

Q: Is this an original Yamaha part? A: No, this is an aftermarket replacement made to match the 6EY-81940-09-00 reference. It is designed to fit and function in the same location as the factory part.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
