How To Bypass Obc On Club Car

The Club Car’s onboard computer (OBC) is a vital component that regulates various functions, including battery charging, speed control, and safety features. However, in certain situations, bypassing the OBC may be necessary to troubleshoot issues or enhance performance. This article provides a comprehensive guide on how to bypass the OBC on a Club Car, addressing the potential risks, precautions, and step-by-step instructions.

Understanding the OBC and Its Functions

The OBC is the brain of a Club Car’s electrical system. It monitors and controls the flow of electricity from the batteries to the motor, ensuring optimal performance and safety. The OBC also regulates the charging process, preventing overcharging and extending battery life. Additionally, it provides diagnostic information and error codes, aiding in troubleshooting.

Potential Risks and Precautions

Before attempting to bypass the OBC, it’s crucial to understand the potential risks and take necessary precautions:

  • Electrical Damage: Bypassing the OBC can disrupt the electrical system, potentially damaging components such as the motor, batteries, or controller.
  • Fire Hazard: Improper bypassing can create electrical arcs or short circuits, increasing the risk of fire.
  • Safety Concerns: The OBC plays a role in safety features such as speed limiting and braking. Bypassing it may compromise these functions.
  • Warranty Void: Modifying the electrical system may void the manufacturer’s warranty.

How to Bypass OBC on Club Car – Step-by-Step Instructions

Materials Required:

  • Multimeter
  • Electrical tape
  • Wire cutters
  • Crimp connectors


  1. Disconnect the Battery: Ensure the Club Car is turned off and the battery is disconnected.
  2. Locate the OBC: The OBC is typically located under the seat or in the battery compartment.
  3. Identify the Wires: Using a multimeter, identify the following wires:
    • Red: Positive battery input
    • Black: Negative battery input
    • Yellow: Output to the motor
  4. Cut the Red Wire: Cut the red wire connecting the battery to the OBC.
  5. Connect the Red Wire Directly: Connect the cut end of the red wire directly to the yellow wire going to the motor.
  6. Insulate the Connection: Wrap electrical tape around the connection to prevent short circuits.
  7. Reconnect the Battery: Reconnect the battery and turn on the Club Car.

Troubleshooting and Conclusion

After bypassing the OBC, observe the Club Car’s operation carefully. If any issues arise, such as excessive speed or charging problems, it’s recommended to consult a qualified technician.

Bypassing the OBC can be a useful troubleshooting technique or a performance enhancement for certain applications. However, it’s crucial to proceed with caution, taking necessary precautions to minimize risks. Always refer to the manufacturer’s instructions and seek professional assistance if needed.
