Good To Know

Q: How do I know the solenoid is the problem? A: A single loud click with no crank often points to worn solenoid contacts. Testing voltage at the switch terminal while cranking confirms whether the solenoid is switching properly.

Q: Is this an original Yamaha part? A: This is a replacement starter solenoid made for Yamaha applications that cross-references OEM 1B7-81940-00-00. It is not an original Yamaha-branded part.
