Compatibility & Fitment

• Designed for high-amperage 12VDC switching applications.
• Commonly used in golf carts, including EZGO Marathon (1979-1994).
• Suitable for automotive, marine, and industrial winch control systems.
• Functions as a battery isolator or high-current power relay for campers and utility vehicles.

When to Replace

• Vehicle or equipment will not start or engage.
• Audible clicking from the solenoid without motor activation.
• Intermittent operation of the connected system (e.g., starter, winch).
• Solenoid fails to disengage, causing the motor to continue running.
• Visible signs of corrosion, arcing, or physical damage to terminals or housing.

Installation Tips

• Disconnect the negative battery cable before starting work.
• Ensure all electrical contact points and cable ends are clean and free of corrosion.
• Mount the solenoid in a location away from direct water exposure and excessive heat.
• Securely tighten all nuts on the terminals, but do not overtighten to prevent damage to the studs.
• Verify correct wiring for both the high-current posts and the smaller activation terminals.
