Club Car Speed Sensor Bypass

Disclaimer: Bypassing or modifying your golf cart’s speed sensor is not recommended, as it may violate local laws, void warranties, or even compromise safety. Proceed at your own risk.


The Club Car Speed Sensor is a device designed to control the maximum speed of electric Club Car golf carts. The sensor works in tandem with the motor controller to regulate the speed and protect the motor from potential damage. However, some enthusiasts seek ways to bypass or modify the speed sensor to increase their golf cart’s top speed. This article provides an overview of the process, though it is important to reiterate that doing so carries potential risks and may not be legal in your area.

Materials You’ll Need

  1. Multimeter
  2. Wire cutters
  3. Wire strippers
  4. Electrical tape
  5. Heat shrink tubing
  6. Soldering iron and solder
  7. A 2-wire harness or two single wires
  8. Small zip ties

Step-by-Step Guide

  1. Ensure safety first: Before beginning, ensure that the golf cart is turned off, the key is removed, and the cart is in a secure position to prevent any movement.
  2. Locate the speed sensor: The speed sensor is typically located on the end of the motor, near the rear axle. It is a small, cylindrical device with wires leading to the motor controller.
  3. Disconnect the speed sensor: Carefully unplug the speed sensor connector from the motor controller. Keep track of the wires, as you’ll need to work with them later.
  4. Identify the wires: There should be two wires coming from the speed sensor. One wire will be the signal wire, and the other will be the ground wire. You can use a multimeter to identify which wire is the signal wire by measuring the voltage while the cart is moving. The signal wire will show a fluctuating voltage, while the ground wire will show a stable 0V.
  5. Prepare the bypass: Cut the signal wire about 2 inches away from the speed sensor. Strip both ends of the wire, revealing approximately ¼ inch of bare wire. Use the wire harness or the two single wires, and strip their ends as well.
  6. Connect the bypass: Solder one end of the wire harness or single wire to the signal wire coming from the speed sensor. Solder the other end to the signal wire leading to the motor controller. Ensure that the connection is secure and wrap it with electrical tape.
  7. Insulate and secure the connection: Slide heat shrink tubing over the soldered connection and apply heat to secure it in place. Use small zip ties to keep the bypass wires neat and away from any moving parts.
  8. Reconnect the speed sensor: Plug the speed sensor connector back into the motor controller.
  9. Test the bypass: Turn on the golf cart and test its performance. If the bypass was successful, you should notice an increase in top speed. Be aware that bypassing the speed sensor can strain the motor and potentially lead to damage or failure.

Please note that this information is for educational purposes only and attempting to bypass the speed sensor can result in voiding any warranties or causing potential harm to your golf cart. Proceed at your own risk.

1Gather necessary tools and materials, such as a multimeter, wire strippers, connectors, and electrical tape.
2Disconnect the golf cart’s battery to prevent any electrical issues while working.
3Locate the speed sensor on the motor, typically on the end of the motor opposite the drive shaft.
4Disconnect the speed sensor’s wiring harness from the motor controller.
5Identify the two wires that are responsible for the speed sensor signal, usually green and white.
6Cut the green and white wires near the speed sensor, leaving enough wire to work with on both ends.
7Strip the ends of the green and white wires, both from the speed sensor and the wiring harness.
8Connect the green wire from the speed sensor to the white wire on the wiring harness, and vice versa, using connectors or soldering. This will create a loopback signal, effectively bypassing the speed sensor.
9Use electrical tape to insulate and secure the connections, ensuring no exposed wires can cause a short circuit.
10Reconnect the golf cart’s battery and test the cart to ensure the bypass was successful.

As shown in the below table, bypassing a Club Car speed sensor comes with several risks and downsides. It’s important to consider these factors before deciding to bypass the sensor, and always follow the manufacturer’s guidelines and consult a professional technician if you are unsure of any steps


SpeedPotentially increased top speedCan lead to motor overheating or damage
SafetyNoneReduced safety due to lack of speed control
WarrantyNoneLikely to void any warranties on your golf cart
ControlIncreased control over speed adjustments and limitationsRisk of overloading the motor and causing mechanical issues
