Good To Know

Q: How do I know if my solenoid has failed? A: A single loud click with no crank usually points to a solenoid that is no longer passing current to the starter, though battery and cable condition should be checked first.

Q: Is this an original Yamaha part? A: This is an aftermarket starter solenoid built to the 1B7-81940-00-00 cross-reference and is not an original brand product.

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