how to bypass starter solenoid on tractor

Tractors are an essential piece of equipment for farmers and ranchers alike. However, like any other machinery, tractors may fail to start because of various reasons. One of the common issues is a failed starter solenoid. The solenoid connects the battery to the starter motor that cranks the engine. When a starter solenoid fails, the tractor will not start at all. Fortunately, bypassing the starter solenoid can solve the problem. This article will offer step-by-step guidelines on how to bypass starter solenoid on tractor.

Tools required

Before attempting to bypass the starter solenoid, you will need a few tools. These include a pair of pliers, a wrench, a screwdriver, a multimeter, and an electrical wire.

Identifying the starter solenoid

The starter solenoid is located on the tractor's starter or near the battery. It is usually cylindrical in shape with two or three posts. One post connects to the battery, while another post connects to the starter motor. The third post is the trigger, which connects to the tractor's electrical system.

Bypassing the starter solenoid

To bypass the starter solenoid, you will require an electrical wire. First, disconnect the battery's negative terminal to prevent any risk of electrical shock. Secondly, use a wrench to remove the wires from the starter solenoid's posts. The wires connecting to the solenoid should be labeled, and it is essential to label them to avoid confusing them while reconnecting. Next, cut a six-inch length of electrical wire and strip both ends using pliers. Connect one end of the wire to the battery's positive terminal and the other end to the starter motor's post. Reconnect the battery's negative terminal and try to start the tractor.

Testing continuity

After bypassing the starter solenoid, it is essential to confirm if there is continuity between the battery and the starter. To test continuity, use a multimeter set to resistance or ohms. Place the multimeter leads on the starter motor and the battery's positive terminals while keeping the ignition off. You should observe zero to minimal resistance on the multimeter, indicating there is continuity. The continuity test ensures that the electrical wire is not damaged, and the electrical circuit is complete.

Conclusion

Bypassing the starter solenoid on a tractor is a simple process that can save time and money. It is essential to have the necessary tools, follow the procedure carefully, and test continuity after bypassing. However, if the starter solenoid continues to fail, it is recommended to replace it to avoid any long-term damage to the tractor's electrical system.
