Good To Know

Q: How do I know the solenoid is the problem? A: If the starter will not turn but the battery is charged, and you hear only a click or nothing at all, the starter solenoid relay is a common cause on these Honda ATVs.

Q: Does this need any wiring changes? A: No, this relay uses the factory-style terminal layout, so the battery and starter cables connect the same way as the original part.

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