In this blog post, we’ll explain how to bypass a solenoid on a golf cart, as well as provide some key tips and advice. Keep reading to learn all about how to get your golf cart up and running in no time!

Understanding the Solenoid 

A. Definition and role of the solenoid in a golf cart’s electrical system

The solenoid is an important component in the electrical system of a golf cart. It is a type of electric relay that is used to control the flow of electricity to the golf cart’s motor. Solenoids are responsible for accelerating the motor when a voltage is applied to the coil, creating a magnetic field that pulls the plunger, which moves the motor. In short, the solenoid controls the speed and power of the golf cart, allowing it to move effectively.

B. Explaining common reasons for needing to bypass the solenoid

There may be several causes for needing to bypass the solenoid, including a dead battery, faulty electrical system, or a burned-out solenoid. By bypassing the solenoid, the owner can get the golf cart to run without having to replace the entire electrical system system. This can be a much cheaper and quicker alternative than replacing the entire system which can be both time consuming and expensive. 

C. Risks and precautions associated with bypassing the solenoid

Bypassing the solenoid may lead to a number of issues, as the solenoid helps to regulate the flow of electricity to the motor, so any problems with the motor may be worsened without it. Also, bypassing the solenoid may cause it to get more heat than it can handle, and this can damage the electric motor. There are several precautions that should be taken when bypassing the solenoid in order to avoid any issues. It is important to make sure the voltage applied to the coil is not too high, as this can damage the motor and solenoid. Also, if the motor is not working properly, it is important to check the voltage levels on the electrical system before bypassing the solenoid. Finally, it is important to be careful when connecting the wires of the solenoid to ensure that extra voltage is not applied to the motor.

Assessing the Situation 

A. In order to decide whether bypassing the solenoid is necessary or a temporary solution, it’s important to assess the situation. Some factors to consider are the age of the golf cart and whether the solenoid had been replaced recently. It’s also important to think about the conditions of the surrounding environment and any pressure that may be applied to the solenoid in order to determine whether bypassing the solenoid is the right solution.

B. Identifying potential issues causing the solenoid to malfunction can help to determine if bypassing the solenoid is the best solution. Common problems can include wiring issues, corrosion, or a weak battery. A qualified technician should be able to run through a checklist of potential problems before deciding whether bypassing the solenoid is the right solution.

C. Checking for alternative solutions or troubleshooting steps before bypassing is always recommended. If possible, it is best to try and find the root of the problem in order to resolve it. This includes checking the wiring and battery, as well as testing if the solenoid is receiving enough power. If the solenoid is still not functioning after troubleshooting, bypassing the solenoid may be the only solution.

Preparing for Bypassing 

A. Before beginning the bypassing procedure, it is important to gather all the necessary tools and equipment. This includes safety supplies such as safety goggles, face mask, and gloves. Other items may include a socket set, wrenches, wire cutters, and electrical tape.

B. It is also important to make sure that personal safety measures are taken before attempting to bypass a solenoid. This includes wearing protective gloves and eye protection to prevent injury or exposure to electrical shock. Additionally, it is important to ensure that all tools are securely held and that any exposed wires are insulated.

C. Once all safety precautions are taken, locate the solenoid and understand how its wiring connections will be used to bypass the solenoid on a golf cart. Make sure to identify the ground, voltages, and current paths. Following a diagram of the solenoid can help in understanding how to make connections correctly.

Step-by-Step Guide to Bypassing the Solenoid 

A. Step 1: Disconnect the battery from the power source and then remove the negative (-) cable first, followed by the positive (+) cable.

B. Step 2: Locate the solenoid, which is usually found near the battery and motor of the golf cart. Connect the negative (-) battery cable back to the battery post, and then identify the solenoid’s positive and negative wiring connections and disconnect them both.

C. Step 3: Disconnect both of the main power wires from the battery and secure them to the outside of the battery post screw terminals.

D. Step 4: Connect a single jumper wire between the positive and negative terminals of the solenoid. Secure it to the screw terminals with electrical tape to prevent any sparks. This will create a direct current circuit so power will flow from the battery to the controller.

E. Step 5: Now it is necessary to bypass the external electrical components of the golf cart. Place a jumper wire in parallel to the ignition switch, and then attach a resistor in series with the starter motor relay.

F. Step 6: Reconnect the main power wires to the battery. This should complete the bypass of the solenoid and the golf cart should now be running off the primary battery.

Safety Considerations and Limitations 

Safety considerations when bypassing the solenoid on a golf cart include:

1. Make sure to disconnect the battery before attempting any work on the golf cart solenoid.

2. Ensure that the correct wiring diagram for the solenoid bypass is obtained and understood, and that the correct wires are used in the bypass.

3. Make sure all necessary instructions are followed for the bypass.

4. If the golf cart is a part of a class from a school or tournament, then follow any regulations that may be in place.

5. Do not attempt to bypass the solenoid if you do not have proper electrical experience and training. Inexperienced work may result in personal injury, damage to the golf cart, or even death.

Limitations of bypassing the solenoid include:

1. Bypassing the solenoid may void the warranty of the golf cart.

2. Bypassing the solenoid should only be done as a temporary fix and not as a permanent solution.

3. Over time, bypassing the solenoid may cause the components of the golf cart to wear out.

4. If the bypass fails, the golf cart may be inoperable.

5. Bypassing the solenoid may reduce performance and speed of the golf cart.

Reinstalling or Replacing the Solenoid 

A. As the primary switching device in a golf cart’s electrical system, the solenoid is responsible for controlling the flow of electricity to the cart’s motor and other electrical components. Thus, it is essential for proper cart functioning that the solenoid is in good working order. If the solenoid has become corroded, dirty, or otherwise damaged, it may need to be replaced or reinstalled.

B. In order to properly install or replace a solenoid, it is important to have the right tools and knowledge of electrical systems. Developing a plan of attack and familiarizing oneself with the parts and how they fit together can save time and frustration. Generally speaking, the process of installing or replacing a solenoid involves 1) locating and disconnecting the power lead from the battery, 2) locating and disconnecting the wire that goes to the motor from the solenoid, 3) removing and inspecting the solenoid, and 4) reinstalling the solenoid, with any needed cleaning or replacement parts, and reassembling the wire connections.

C. If the installation or replacement of a golf cart’s solenoid appears to be beyond an individual’s skill or comfort level, it is a good idea to consult a golf cart expert or technician. He or she can provide valuable assistance in properly installing or replacing the solenoid to ensure optimal performance. It is also important to note that in some cases, it may be easier to simply bypass the solenoid, rather than remove and reinstall it. A golf cart technician can provide guidance and instructions for how to bypass the solenoid, if necessary.


By following the instructions in this article, you should now have a good understanding of how to bypass a solenoid on a golf cart. By being familiar with the process, you can now save yourself time and money while avoiding potential problems with your cart. In addition, you should have a better idea of how to find and purchase the right solenoid for your golf cart. Remember to always keep safety in mind when performing any type of repair or maintenance on your golf cart.
