Good To Know

Q: How do I know my solenoid needs replacing? A: A single loud click with no crank, or inconsistent starting, usually points to worn internal contacts in the solenoid. Testing voltage at the starter terminal while cranking confirms whether the relay is passing current.

Q: Is this an original Yamaha part? A: No, this is an aftermarket starter solenoid built to replace OEM part 1B7-81940-00-00. It is designed to match the fit and function of the factory component.

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