Gaoerfu-CP EZGO 36V #70 Series Solenoid Relay for TXT/Marathon 1980–2010 — OEM Fit, Copper Contacts

The Gaoerfu-CP EZGO 36V #70 Series solenoid is a direct-replacement start solenoid designed to restore reliable electrical connection between the battery pack and starter circuit on EZGO TXT and Marathon electric golf carts (1980–2010).

This heavy-duty replacement solenoid fits 36‑volt EZGO TXT and Marathon models made between 1980 and 2010 and matches multiple OEM part numbers so you can swap it in without modifying the wiring harness. Built with copper-alloy contacts, an insulated base, and a steel housing, it’s engineered for robust conductivity and frequent start cycles. Follow installation guidance about terminal torque and diode orientation to ensure safe, long-lasting performance.

How does this solenoid restore my golf cart’s starting performance?

The solenoid acts as the electrical bridge that closes the high-current circuit when you turn the key, allowing battery power to reach the starter and drive systems. Replacing a failed unit removes internal contact wear or coil faults that prevent the cart from starting.

• Directly replaces OEM numbers like 27855G01, 11761G1, 27855G02 and others
• Copper-alloy contact terminals improve conduction and reduce voltage drop
• Four-terminal layout matches factory wiring for plug-and-play swaps
• Steel housing and insulated base for durable mounting and safety

What installation steps and precautions should I follow?

Installation is straightforward if you disconnect batteries first and carefully transfer the wiring. Avoid over-tightening terminal nuts, confirm the small diode’s orientation, and recheck all connections before restoring power.

• Always disconnect the battery pack before beginning work
• Torque terminals snugly but do not overtighten to prevent damage
• Ensure the diode line points toward the positive terminal as marked
• Test operation with key start and inspect for unusual heating or arcing

Is this unit suitable for continuous duty and high-current use?

This solenoid is a start solenoid designed for frequent starting rather than sustained continuous current. It can handle short bursts of high current but should be given breaks between extended runs to avoid overheating.

• Rated for start-duty operation on 36V systems used in EZGO carts
• Can withstand up to ~150A for short intervals but will heat under extended load
• Not intended to run continuously for long durations without cooling breaks
• Use as directed to prolong contact and coil life

Who is this for: Technicians, fleet managers, and DIY golf-cart owners who need a reliable OEM-compatible replacement for EZGO TXT and Marathon electric carts (1980–2010). If your cart shows no cranking when the key is turned, has intermittent starting, or exhibits high resistance at the starter terminals, this Gaoerfu-CP solenoid offers a cost-effective route to restore dependable starts while matching the original factory fit and mounting points.
