Chapter 1: When the Golf Cart Doesn’t Start

Arguably the most frustrating issue is when your golf cart refuses to start. Here are some areas to inspect if you encounter this issue:

Battery Inspection

The first thing to check when your golf cart won’t start is the battery. A battery with inadequate charge or corroded terminals could prevent the cart from starting. Check if the battery is properly connected and clean, with no visible damage or acid leaks.

A multimeter can be used to check if the battery is holding a charge. For a 36-volt golf cart, the reading should be around 38 volts, and for a 48-volt golf cart, it should be approximately 50 volts.

Key Switch Examination

If the battery seems fine, the next step is to inspect the key switch. The key switch is an integral part of the ignition system. If it’s faulty, it can prevent the cart from starting. Use a multimeter to check for continuity in the key switch when it’s turned on. If there’s no continuity, the key switch might be defective and require replacement.

Chapter 2: Golf Cart Loses Power or Speed

If your golf cart is losing power or speed, several components could be the culprit, including the battery, the motor, or the speed controller.

Battery Inspection

Begin by checking the battery. Inspect the water level in each of the battery cells. If it’s low, replenish with distilled water until it reaches the recommended level. Avoid overfilling as it can lead to acid spills. Also, inspect the battery cables and terminals for any signs of corrosion or loose wires that could affect power transmission.

Motor Testing

If the battery is in good condition, you should test the motor. You can do this by disconnecting the motor from the speed controller and using a multimeter to check the motor’s resistance. If the motor’s resistance falls outside the specified range, it may be failing and need replacement.

Speed Controller Evaluation

A faulty speed controller can also cause a golf cart to lose power or speed. You can check the speed controller by using a multimeter to measure the output voltage when the accelerator is pressed. If the output voltage doesn’t increase with the pressure on the accelerator, the speed controller might need to be replaced.

Chapter 3: Golf Cart Stops Suddenly

A sudden stop during operation can be alarming. This issue can be due to problems with the battery, solenoid, or speed controller.

Battery Examination

Start by examining the battery. Check its voltage using a multimeter while the golf cart is in operation. If the battery’s voltage drops significantly while driving, it may be a sign that the battery is failing.

Solenoid Assessment

The solenoid is a vital component that acts like a switch controlling the large amount of current required by the motor to run the golf cart. Use a multimeter to check both the solenoid’s input and output voltage. If there’s no voltage output when the accelerator is pressed, it may suggest that the solenoid is defective and needs replacement.

Chapter 4: Golf Cart Battery Drains Fast

A battery that drains too quickly can be another common problem in electric golf carts. This could be a sign of a defective battery or a drain in the electrical system.

Battery Test

You can test the battery using a hydrometer to check the specific gravity of each cell. A hydrometer measures the density of the battery acid, which can indicate the health of the battery. A significantly low reading in one or more cells can indicate a bad cell, which can cause the battery to drain quickly.


Electric golf carts, while extremely convenient, require routine maintenance and occasional troubleshooting. Knowing how to identify and resolve common problems not only ensures a smooth ride but also contributes to the longevity of your golf cart. This guide serves as a comprehensive resource to diagnose and troubleshoot the most common issues. However, when in doubt, always consult the golf cart’s manual or seek professional help to avoid causing more damage. As an electric golf cart owner, your adventures on and off the green are made more reliable and efficient by your ability to maintain and care for your vehicle.
