1994 EZGO Marathon Wiring Diagram: A Comprehensive Guide

Electric carts or golf carts have become a popular mode of transportation for people who want to move around small areas, such as golf courses, resorts, and theme parks. If you own a 1994 EZGO Marathon electric cart, it’s important to understand its electrical system, including its wiring diagram, to ensure proper functioning.

What is a Wiring Diagram?

A wiring diagram is a visual representation of the electrical system in a vehicle, which shows how the various components are connected and how electricity flows through the system. It’s like a map that guides you in troubleshooting and repairing electrical issues in your cart.

Why is the Wiring Diagram Important?

The wiring diagram is important because it helps you identify electrical problems in your cart. It also guides you in replacing components, testing switches, and repairing connections. Without a wiring diagram, you may end up wasting time and money replacing components that are not faulty, or not knowing where to start troubleshooting.

Understanding the Wiring Diagram

The 1994 EZGO Marathon wiring diagram may seem daunting, but it’s relatively easy to understand if you break it down into sections.

The Battery System

The battery system is the heart of the electrical system in your cart. The six 6-volt batteries are connected in series to produce a 36-volt system. The red wire connects the series positive terminal to the main positive terminal, while the black wire connects the series negative terminal to the main negative terminal.

The Solenoid

The solenoid is an electrical switch that connects the battery pack to the motor controller when the accelerator pedal is depressed. The yellow wire connects the main positive terminal to the M- F2 terminal on the solenoid, while the blue wire connects the solenoid’s B+ A2 terminal to the reverse switch. The orange/white wire connects the solenoid’s B+ A1 terminal to the forward switch.

The Motor Controller

The motor controller is responsible for regulating the current that flows to the motor, which determines the speed of the cart. The green wire connects the main negative terminal to the B- terminal on the motor, while the grey wire connects the A+ terminal on the motor to the motor controller. The brown wire connects the A- terminal on the motor to the motor controller.

The Key Switch

The key switch is used to turn on and off the cart. The purple/white wire connects the key switch’s ignition terminal to the positive battery terminal.

The Charger

The charger is used to recharge the battery pack. The pink wire connects the charger’s positive F1 terminal to the main positive terminal, while the black/pink wire connects the charger’s B- terminal to the solenoid’s B- terminal.

FAQ

1. How do I troubleshoot my cart’s electrical system?

Use the wiring diagram as a guide to identify the source of the problem. Check the batteries to ensure they are charged and connected properly. Test the solenoid, motor controller, forward/reverse switch, and key switch using a multimeter.
