Good To Know

Q: How do I tell the solenoid is the problem and not the starter? A: A single loud click with no crank often points to the solenoid, while a slow grind usually points to the starter or battery. Test voltage at the starter terminal when the button is pressed to confirm.

Q: Is this a genuine Yamaha part? A: This is an aftermarket starter solenoid built to replace the listed OEM number, not an original Yamaha-branded component. Cross-reference the part number against your machine before ordering.

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