Understanding the 36 Volt EZGO Golf Cart Electrical System
Before diving into the wiring diagram specifics, it’s vital to understand the overall electrical setup of a 36-volt EZGO golf cart.
Key Components of the System
- Battery Pack: Typically consists of six 6-volt batteries connected in series to provide 36 volts.
- Controller: Manages motor power based on accelerator input.
- Motor: Usually a DC motor that propels the cart.
- Forward/Reverse Switch: Changes the motor’s direction.
- Solenoid: Acts as a high-current relay to control motor engagement.
- Throttle Pedal: Sends signals to the controller for speed regulation.

Role of the Forward Reverse Switch in a 36V EZGO Cart
The forward/reverse switch is crucial for controlling the direction of the golf cart. It enables the driver to select whether the cart moves forward or backward without changing the motor wiring.
How the Switch Works
- When set to “Forward,” the switch completes a circuit that directs current to the motor in a way that moves the cart forward.
- When switched to “Reverse,” it reconfigures the wiring to reverse the motor’s polarity, causing the cart to move backward.
- The switch is typically a toggle or a lever with two positions, wired into the main circuit to change the motor’s polarity accordingly.

Wiring Diagram Overview for the 36 Volt EZGO Forward Reverse Switch
The wiring diagram illustrates how the components connect, ensuring the correct flow of electrical current when switching between forward and reverse.
Basic Wiring Path
- Battery pack connects to the main terminals of the solenoid.
- The solenoid acts as the main switch controlling power flow to the motor.
- The forward/reverse switch is wired between the controller, solenoid, and motor to determine the direction.
- The accelerator pedal signals the controller to regulate motor speed.
Important Wiring Points
- Ensure all batteries are properly connected in series, maintaining correct polarity.
- The solenoid’s large terminals connect directly to the battery pack’s positive terminal and the motor.
- The small terminals on the solenoid connect to the controller, forward/reverse switch, and accelerator pedal.
- The forward/reverse switch connects to the controller and motor wiring to change the polarity depending on the selected direction.

Step-by-Step Wiring Instructions
Proper wiring ensures safe operation and longevity of the golf cart’s electrical components. Follow these steps carefully:
Tools and Materials Needed
- Screwdrivers and wrenches
- Wire strippers and crimpers
- Replacement wires (appropriate gauge)
- Electrical tape or heat shrink tubing
- Multimeter for testing
Wiring Procedure
- Prepare the Battery Pack: Connect all six 6-volt batteries in series, ensuring correct polarity (positive to negative connections). Use appropriate gauge wires and secure connections tightly.
- Connect the Main Power: Attach the positive terminal of the battery pack to the large terminal of the solenoid.
- Wire the Solenoid: Connect the other large terminal of the solenoid to the motor’s positive terminal.
- Connect the Controller: Wire the controller’s main input terminals to the solenoid and motor as specified by the manufacturer.
- Wiring the Forward/Reverse Switch:
- Identify the switch’s terminals (usually labeled F, R, and common).
- Connect the switch’s common terminal to the controller and the solenoid’s control circuit.
- Connect the F (forward) terminal to the controller or motor wiring as per diagram.
- Connect the R (reverse) terminal similarly, ensuring proper polarity reversal when switched.
- Throttle Wiring: Connect the accelerator pedal to the controller’s throttle input as per the controller’s wiring diagram.
- Testing: Use a multimeter to verify connections, ensuring correct voltage and continuity.

Common Wiring Diagram Variations and Tips
Wiring diagrams can vary slightly depending on the model year and specific EZGO golf cart configuration.
Typical Variations
- Different brands of forward/reverse switches may have varying terminal labels.
- Some models incorporate additional safety features like reverse lockouts or speed controllers.
- Wiring color codes might differ; always verify with the manufacturer's diagram.
Tips for Troubleshooting
- Check All Connections: Loose or corroded terminals can cause malfunction.
- Use a Multimeter: Test for voltage at various points to diagnose wiring issues.
- Verify Switch Functionality: Ensure the forward/reverse switch toggles correctly and is wired properly.
- Consult Manufacturer Diagrams: Always refer to the specific wiring diagram for your cart model.
