Specs At A Glance

Good To Know

Q: How do I know if my solenoid is bad? A: A single loud click with no crank, or no response at all when the start button is pressed, often points to a failed solenoid. Confirming voltage at the trigger wire and across the main terminals helps verify the diagnosis before ordering.

Q: Can I install this myself? A: Yes, the solenoid mounts with basic hand tools and connects to standard battery, starter, and trigger wiring. Disconnect the battery first and match the wiring layout to the original before tightening the terminals.

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