What Is A Golf Cart Solenoid And How Does It Work?

A golf cart solenoid is a crucial electrical component that helps in the running of electric and gas-powered golf carts. This device serves as an on/off switch for power sent from the battery to various parts of the vehicle, including the motor, controller, and accelerator.

Understanding The Function Of A Golf Cart Solenoid

The primary function of a golf cart solenoid is ensuring that electricity flows through the system properly. When you turn on your golf cart, the switch sends a signal to the solenoid. The solenoid then uses magnetic force to create a contact point between its two poles, allowing energy from the battery to reach the rest of the cart’s electrical components. When you press down on the accelerator pedal, it signals the controller to supply power to the solenoid, which again connects the circuit for energy to flow.

It’s important to note that without proper wiring and connection, the solenoid will not work correctly, leading to other issues with the golf cart. Additionally, if the solenoid fails to make contact when triggered by both the ignition key and acceleration pedal, the whole system may shut down completely.

Components Of A Golf Cart Solenoid

  • Coil: This part consists of copper wires wrapped around a metal core, often made of iron or steel. Once connected to the negative pole, this coil creates a magnetic field and leverages the force necessary to trigger the contacts within the solenoid itself.
  • Contact Discs: These are disks found inside the solenoid that connect when electrical current passes through them.
  • Plunger and Spring: The plunger inside the solenoid acts as a bridge between the contacts, or disks. When electrical energy causes the coils to activate, the plunger moves against a spring force that works to prevent it from sticking in one place.
  • Contacts: These disks allow electrical current to flow through them when contacted by the plunger.
“The solenoid is ‘essentially a relay’ that sits in an engine’s high-power circuit and switches power to its starter motor.” -How Stuff Works

You may need to test your golf cart solenoid at some point, especially if you notice issues with starting the vehicle or powering certain features such as headlights or accessories. To do so, start by checking continuity across the two large terminals on the device using a voltmeter while the ignition key is turned off. If there is continuity, then this indicates that your solenoid has a short circuit problem.

If there is no continuity present, you can perform another test while the ignition is turned on. Use the same multimeter to measure resistance across the small wires attached to the bass post. A resistance reading of zero means that the component is working correctly while anything above zero likely requires repairs or replacement.

Hence, proper testing of golf cart solenoids can help ensure optimal functionality, preventing unexpected shutdowns and costly breakdowns.

Tools Needed To Test A Golf Cart Solenoid

Digital Multimeter

A digital multimeter is a must-have tool when testing a golf cart solenoid. It measures voltage, current, and resistance, which are three key parameters that need to be checked during the testing process.

To use a digital multimeter for testing a golf cart solenoid, you need to set it to measure DC volts. Then, connect the red lead to the positive terminal of the battery and black lead to the negative terminal. Next, touch the leads to the input terminals of the solenoid while someone else steps on the accelerator pedal. This will activate the solenoid, and you can check if it’s functioning properly by looking at the readings on your multimeter display.


You’ll need a few different types of screwdrivers to test a golf cart solenoid. The most important one is a Phillips-head screwdriver, which is used to loosen and remove the screws that hold the solenoid in place.

Once you’ve removed the screws, you can disconnect all wires from the solenoid. Pay close attention to where each wire connects so you can reassemble everything correctly later on.

Alligator Clips

Alligator clips come in handy when testing a golf cart solenoid because they allow you to easily and securely attach wires to various parts of the solenoid. They’re especially useful for attaching the multimeter leads to the input terminals of the solenoid.

To use alligator clips for testing a golf cart solenoid, simply clip them onto the ends of the multimeter leads and then clip the other end onto the appropriate terminal of the solenoid. Make sure everything is tightly connected so that you get accurate readings on your multimeter display.

“The solenoid is a key part of any golf cart’s electrical system, and it’s important to test it regularly to ensure proper functioning.”

By having these tools at your disposal, you’ll be able to thoroughly test the golf cart solenoid and identify any potential issues. This will save you time and money in the long run by preventing breakdowns and costly repairs.

Step-By-Step Guide To Testing A Golf Cart Solenoid

Golf carts are a great way to get around the golf course, but when they break down, it can be frustrating. If you suspect that the issue is with your golf cart solenoid, then you will want to test it to see if that is indeed the case. Here’s how:

Disconnecting The Battery

The first step in testing a golf cart solenoid is to disconnect the battery. This is an important safety measure because the system carries high voltage that can cause injury or damage. Once the battery has been disconnected, you can proceed with the testing.

To disconnect the battery, start by turning off the ignition on your golf cart, and removing the key from the switch. Next, locate the batteries (typically located under the seat) and turn the battery cut-off switch to “off”. At this point, use a wrench to remove the negative cable terminal from the battery. You should also cover the exposed end of the cable with electrical tape to prevent accidental contact during the next steps.

Locating The Solenoid

Once the battery has been disconnected, the next step is to locate the golf cart solenoid. In most cases, the solenoid will be located near the golf cart controller. You might need to refer to your user manual or ask for professional help if you are unsure where the solenoid is located.

The easiest way to find the solenoid is to trace the large red cable coming out of the positive side of the battery, as this wire often leads straight to the solenoid. It may be necessary to remove covers or panels to access the solenoid directly, so make sure to consult your manual before doing so.

A solenoid usually looks like a cylindrical switch with multiple wires attached to its body. The shape and design of the solenoid might vary depending on your golf cart model or manufacturer.

“Golf is an awkward set of bodily contortions designed to produce a graceful result.” -Tommy Armour
  • Step 1: Clean The Contacts
  • The contacts in the solenoid are essential in regulating energy flow between the battery, motor, and controller. Cleaning the contacts can help improve solenoid operation and identify issues if there’s any resistance. You will need a soft-bristled brush and contact cleaner for this step.

    To clean the contacts, use the brush to remove dirt, dust, or corrosion from within the switching mechanism. Once done, spray some contact cleaner onto the contacts, ensuring that you cover all visible surfaces.

  • Step 2: Check For Resistance
  • You can examine solenoid resistance using a multimeter. A good testing procedure will involve checking the continuity across all connections as you transmit electricity through them. Connect the positive port of your meter to one of the small posts and the negative port to the other post on the same side.

    If readings were close-to-zero or zero, then the solenoid’s coil is intact. If it’s higher than 0.3 ohms, then chances are some connections or coil is broken, causing the solenoid not to operate at full capacity. Carry out the same process on the opposite two posts; the reading should be different from the first because now, the power source has shifted to the contact disk terminals across the current path when activated.

  • Step 3: Check Power Supply and Control Circuit
  • The solenoid must receive voltage to work efficiently. You can check if there is power flowing through the contactor by using a voltmeter or multimeter. Attach the positive terminal of the meter to the big post on the input side of the contactor and the negative to any metallic part of the vehicle’s body.

    If you see voltage, that means the problem lies with the control circuitry which needs attention from an expert. In case your reading is zero, try touching the key switch ON and reapply the probe into the same spot; this will allow the full system to pass normal voltage to the solenoid circuit, closing it in the process.

Testing golf cart parts can be very time-consuming, especially when dealing with sophisticated components like a solenoid. However, following these simple steps should help you to troubleshoot potential issues quickly. If you’re still struggling with your solenoid even after testing it, seek professional assistance rather than make matters worse by trying to repair it yourself.
