Specs At A Glance

Good To Know

Q: How do I know the solenoid is the problem? A: A single loud click with no crank often points to the solenoid or its wiring, while a silent start button can mean the switch or battery. Testing voltage at the solenoid terminals confirms where the fault sits.

Q: Do I need to replace the cables too? A: Only if the existing cables show corrosion, swelling, or frayed ends. Clean, tight terminals on sound cables let a new solenoid do its job properly.

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