General Components to look out for When Troubleshooting Ezgo Electric Golf Carts

People often overlook certain issues when troubleshooting their ezgo electric golf carts assuming them to be insignificant however checking for these may prove to be worthwhile, these include,

  • Testing the wall socket to ensure it actually delivers sufficient power to charge the Ezgo electric golf cart batteries. It may prove that the socket is either in bad shape or the circuit wall breaker is off and needs to be reset. Such a test can be carried out using a multi-meter to test the voltage at the terminals. Normal American sockets usually deliver 120V when operating properly, however it may vary hence checking the rated voltage for that particular socket is important.
  • Other parameters to check include checking the Ezgo golf cart battery to ensure it is delivering sufficient voltage, and current. The motor may also be faulty and needing to be reset, repaired or replaced.
  • Other components include headlights, wheels, manual controls such as the horn and steering wheel.

Steps in troubleshooting the Ezgo golf cart

Before carrying out any maintenance work it is important to look at the manual for special safety protocols to follow such as switching of the golf cart before handling any electrical circuits. The following components are important when troubleshooting.

1. The Batteries

Before carrying out any maintenance on the golf cart battery, ensure it is disconnected from the electrical circuits by switching of the key. The batteries used by the ezgo electric golf cart are heavy hence they need proper lifting techniques, also ensure all sources of sparks are kept away from the battery. The electrolyte in the battery may need topping off after several rounds of usage hence ensure proper safety gear is worn. These include safety googles and clothing that protects against acid spills since the electrolyte is acid based. Electrolyte spills can be neutralized using a solution of 1/4 cup (60 ml) sodium bicarbonate (baking soda) dissolved in 1/2 gallons (6 liters) of water and flushed with water.

The battery voltage can be tested using a volt meter set to measure Direct Current Voltage (DC). Place the negative voltmeter probe on the negative terminal and the positive probe on the positive terminal and record the value on the screen then compare with the rated voltage of the battery. The electrolyte level can be measured with a hydrometer while the current drawn at constant voltage is measured with a load tester which will show how long the battery can go before losing power. The batteries in the Ezgo electric golf cart are usually connected in series hence to test each individual battery needs to be disconnected from the pack and tested separately.

2. The motor

The Ezgo electric golf cart motor is a 48V DC shunt wound, brazed armature, solid copper winding motor that delivers 10.2 to 14.8 mph on level ground. It often needs little to no attention however if the golf cart delivers lower power to the wheels and sluggish acceleration it may need to be tested. It has to be isolated from the golf then power can be supplied to it and its revs/minute measured. The motor also allows regenerative breaking capabilities meaning it can charge the battery when the accelerator is released especially on a downhill. This effect is usually tested by noticing a significant reduction in speed when the accelerator pedal is released. Sluggish deceleration may indicate that the motor is faulty and needs replacement.

3. The Brakes and Accelerator

The brakes are a crucial component of the Ez Go electric golf cart as they allow it to come to a stop from higher speeds. Their effectiveness is often noticed by observing longer stopping distances when the brakes are depressed. The Ezgo electric golf cart uses the dual rear wheel mechanical self-adjusting drum brakes and automatic angle point park release with a self-compensating system. The brake fluid level needs to be checked regularly to ensure optimum performance. The foot pedal mechanism may also need checking and re adjusting to ensure it is responsive. The tie rods also need to be checked for excessive play, bent rods and loose or missing hardware. Also check the rear axle for oil leakages, noise or missing hardware.

4. Tires

The tire pressure as well as the overall condition of the tire needs to be inspected regularly to ensure that the tires are in optimal condition. Check the tire pressure daily before use or regularly after 20 rounds or 100miles/160km every month. While checking the tires the suspension may also need to be checked, which is a leaf spring with hydraulic shock absorbers. Check for strut oil leakages, excessive play in the hubs or kingpins, worn bushings and loose or missing hardware. Ensure all four tires have the same pressure level and install the valve stem dust cap after checking and inflating tire pressure. Tires can develop leaks; hence they need to be tested to ensure there are no tire leaks. Also check the tire treads as they give a good indication about the tire deterioration. Also check the wheel alignment which can result in unusual tire wear.

5. Portable charger

Checking the Ezgo golf cart charger is of paramount importance as it allows the batteries to receive the proper charge requirements. Ensure that the correct charger is used and that it delivers the correct voltage and current. Usually, the charger is rated for 48V for the golf cart. Also measure the time it takes to charge the battery pack and compare it against the manufacturer stipulated charging time. If it does not match, the charger may need replacement. Never charge frozen batteries as it may damage the battery. Proper ventilation when charging the battery is also important as it prevents deterioration. Keep away from sources of fires such as sparks, flames or cigarettes. The outlet used for charging should also be properly grounded.

Ezgo electric golf cart chargers need dedicated circuits that can be installed by a qualified professional. When properly charging the charger will flash a green light which goes solid when full. A red flashing light indicates a fault.  A visual inspection of the charger for broken, frayed, loose terminals or exposed connections can provide the source of why the golf cart is not charging. Also check the manual for the different light sequences and what they mean.

6. Controls and indicators

These include the direction selector, state of charge meter, acceleration pedal, combination service or park brake pedal and run-(tow)/maintenance/storage switch. When the corresponding switches are turned on, for example the direction selector when turned to forward or reverse, observe if the golf cart responds to the command appropriately, if not this may indicate that the electronic circuits or mechanical components behind the instrument are malfunctioning and need to be checked preferably by a trained professional.

What not to do

– Do not modify the vehicle so as to affect its weight distribution as this may affect stability and handling when driving.

– Avoid speeding the golf cart on uneven terrain and any other unfavorable environmental conditions such as wet climates.
