10L0L 12V 4-Terminal Solenoid for EZGO TXT & Marathon 1979-1994 — 200A Copper Contacts, Direct-Fit

This 10L0L 12V 4-terminal solenoid is a direct-fit replacement for EZGO TXT and Marathon gas golf carts (1979–1994), providing reliable starter engagement for 2- and 4-cycle engines.

If your EZGO TXT or Marathon golf cart struggles to start or the starter engagement is intermittent, a worn or faulty solenoid is often the cause. The 10L0L solenoid is engineered to restore proper electrical transfer between the battery and starter generator. It matches OEM fit and function, using copper contacts and a 200A DC rating to handle the current demands of the original systems listed under OEM numbers 16542G1 and 16542-1133.

Will this solenoid fit my EZGO TXT or Marathon model?

This replacement is specified for EZGO TXT and Marathon gas carts produced between 1979 and 1994, for both 2-cycle and 4-cycle engines. Match the part to your original solenoid using the OEM numbers to ensure compatibility.

• Fits EZGO TXT and Marathon gas models 1979–1994
• Compatible with 2-cycle and 4-cycle engines
• OEM references: 16542G1, 16542-1133
• Direct-fit 4-terminal mounting pattern

What electrical and physical specs should I expect?

The unit operates at DC 12 volts and is rated to handle up to 200 amps through its heavy-duty copper contacts. It uses four terminals—two large battery/starter posts and two smaller control posts—to replicate the original solenoid’s connections and performance.

• Voltage: 12V DC
• Current capacity: 200A with copper contacts
• 4-terminal configuration for power and control wiring
• Factory-style dimensions and mounting for easy swap-in

How difficult is installation and what tools will I need?

Installation is straightforward if you follow basic safety steps: disconnect the battery, note original wire positions, remove the old solenoid, and transfer wiring to the replacement. Typical installation time is under an hour for someone comfortable with basic electrical connections and hand tools.

• Required tools: wrench or socket set, screwdriver, thread locker optional
• Safety step: fully disconnect battery before starting
• Reuse original mounting hardware or replace with equivalent
• Inspect wiring and terminals for corrosion during installation

How does this solenoid improve starting reliability?

A fresh solenoid restores solid electrical contact between the battery and starter generator so the ignition engages consistently. Using copper contacts reduces resistance and heat buildup compared with corroded or burned original contacts, helping the starter receive full battery power when you turn the key.

• Replaces failing or intermittent starter engagement
• Copper contacts lower electrical resistance for better power transfer
• Factory replacement quality equals original OEM performance
• Helps prevent no-start conditions caused by poor contact

Who this is for: Owners and technicians maintaining EZGO TXT and Marathon gas golf carts from 1979 through 1994 who need a reliable, OEM-style solenoid replacement. This part is aimed at golfers, fleet operators, repair shops, and DIYers who want a direct-fit, durable 12V 4-terminal solenoid that restores proper starter operation without modifications.
