Wiring Your Gas Golf Cart Solenoid: What You Need to Know - The Brassie (2024)

The E-Z-GO Gas Golf Cart is a popular choice for golf enthusiasts and those who enjoy outdoor activities. With its reliable engine and sturdy construction, this golf cart is designed to provide years of enjoyment. However, like any mechanical device, there may come a time when certain components need to be replaced or repaired. One such component is the solenoid, which plays a crucial role in the operation of the golf cart.

The solenoid is responsible for controlling the flow of electrical current to various parts of the golf cart, such as the ignition system and the switch that activates the cart. It acts as a switch, allowing or blocking the flow of electricity depending on the position of the ignition key. When the key is turned on, the solenoid is activated and allows electricity to flow, starting the engine and powering the cart.

When it comes to wiring the solenoid, it is important to ensure that the wires are connected correctly. In most cases, the order of the wires does not matter. However, there are instances when it is crucial to connect the wires in the correct order. For example, if the solenoid is controlling a switch, it is important to make sure that the load wire is connected to the correct terminal. If the wires are connected incorrectly, the circuit may not work properly, and the golf cart may not start or function as intended.

To check if the solenoid is functioning properly, you can perform a simple voltage test. Place the positive probe of a voltmeter to the controller side of the solenoid’s large post. The reading should be approximately 0.1 to 3 volts less than the battery voltage. If the reading is more than 3 volts less than the battery voltage, it indicates a faulty resistor. On the other hand, if the voltage reading is the same as the battery voltage, it is a sign that the solenoid needs to be replaced.

Another way to test the solenoid is by listening for a clicking sound when you step on the gas pedal. The solenoid should make a clicking sound, indicating that it is activating and allowing electricity to flow. Additionally, you can use a multimeter to measure the resistance of the solenoid. A functioning solenoid should have a reading of less than 0.4 ohms. If the reading is higher, it indicates that the solenoid is not working properly and needs to be replaced.

One of the most obvious signs of solenoid failure is when the golf cart fails to turn on when you turn the key. Normally, the solenoid clicks a little with the ignition system in regular operation. However, if the solenoid is failing, it may not make any sound when you turn the key, indicating a problem with its functioning.

The solenoid is an important component of the E-Z-GO Gas Golf Cart, responsible for controlling the flow of electrical current to various parts of the cart. It is crucial to ensure that the solenoid is wired correctly, as incorrect wiring can lead to malfunctions in the cart’s electrical system. Performing voltage and resistance tests can help determine if the solenoid is functioning properly. If signs of solenoid failure, such as a lack of clicking sound or failure to start the cart, are present, it may be necessary to replace the solenoid. Regular maintenance and proper wiring can help ensure the smooth operation of your E-Z-GO Gas Golf Cart.

Does It Matter Which Way A Solenoid Is Wired?

When it comes to wiring a solenoid, in most cases, it doesn’t really matter which way the wires are connected. The solenoid is an electromagnetic device that converts electrical energy into mechanical motion. It typically consists of a coil of wire wrapped around a metal core, and when an electric current flows through the coil, it creates a magnetic field that attracts or repels the core.

In general, the solenoid will function properly regardless of the wire order. However, there are a few situations where the wiring order does matter. Let’s take a closer look:

1. Controlling a switch: If the solenoid is being used to control a switch or relay, it is crucial to ensure that the load wire is connected to the correct terminal. This is because the solenoid’s magnetic field will actuate the switch, and if the load wire is connected to the wrong terminal, the circuit may not work as intended.

2. Polarity-sensitive applications: Some solenoids, especially those used in more specialized applications, may be polarity-sensitive. This means that they require a specific voltage polarity to function correctly. In such cases, it is important to follow the manufacturer’s instructions and connect the positive and negative terminals accordingly.

While the order of the wires may not be critical in most solenoid applications, it is still good practice to follow any provided instructions or guidelines. This ensures proper functionality and avoids any potential issues that may arise from incorrect wiring.

To summarize, when wiring a solenoid, it usually doesn’t matter which wire goes where. However, in situations where the solenoid is controlling a switch or if it is polarity-sensitive, it becomes essential to pay attention to the wire order to ensure proper operation.
