EZGO Marathon Wiring Diagram Overview

This is the EZGO Marathon Wiring Diagram Overview:

  1. Main Wiring Harness: This is the main wiring harness that connects all the other cart components.
  2. Battery Cables: These cables connect the batteries to the rest of the cart.
  3. Solenoid: The solenoid is an electrical switch used to connect and disconnect the battery from the motor. This is what allows the cart to start and stop.
  4. Key Switch: The key switch is used to turn the cart on and off.
  5. Forward/Reverse Switch: This switch is used to control the direction of the cart. It allows the cart to move forward or backward.
  6. Accelerator Pedal: The accelerator pedal controls the cart’s speed. When the pedal is pressed, the motor speeds up, and when it is released, the motor slows down.
  7. Motor: The motor is what drives the cart. It converts the electrical energy from the batteries into mechanical energy to move the wheels.
  8. Charger: The charger is used to recharge the batteries.

The wiring diagram will typically show the connections between these components and how they are connected to the main wiring harness. It will also show the color codes of the wires used for each connection. It is important to have a wiring diagram when working on any electrical system to ensure that the connections are made correctly and to prevent damage to the system or injury to the person working on it.
