Club Car Charging Problems: Reasons and How to Fix

If you own a Club car or probably a golf cart, you’re probably familiar with battery charging. However, you may find yourself stuck if your batteries run out. This can be avoided by ensuring that the car’s battery charger is functioning efficiently. Sometimes the battery charger occasionally fails; hence, one should identify the source of the failure and how to resolve it.

While not every issue can be fixed with a quick do-it-yourself fix, a thorough inspection might save you lots of frustration. Often, the remedy is straightforward, and you can take care of it on a pocket-friendly budget. However, in circumstances where a specialist approach is necessary, the diagnosing process would be accurate. This article will outline various causes of club car charging problems and their corresponding troubleshooting tips.

Reasons for club car charging problems and how to fix them

The car battery is most likely not charging or is rapidly draining. A broken charger, loose cable connections, or perhaps a flat battery are possible causes of charging problems in club cars. Below are various symptoms of club car charging issues and how to go about them;

1. Loose or incorrectly connected wiresClub Car Charging Problems

The cables must be properly linked to complete a circuit for the car battery to power your car. The connection involves the negative cable and the positive. The ground connection is usually made through the negative cable of the battery. The negative cable is normally attached to the car’s body, whereas the positive cable is mounted to the starting unit or the fuse box.

 A faulty wire connection implies that the total current flow will be disrupted, and hence the car battery will not be charged. If the car battery drains, the car will not start, and hence one will be needed to charge it.

Diagnosing a loose wire connection:

To diagnose a loose wire connection, ensure you follow the following techniques to examine why the interface connection is not properly maintained.

  • First, open the battery cabinet, which is normally in the front.
  • Inspect whether the wires are hooked to the appropriate terminals.

Usually, the positive cable is colored red, while the negative cable is black. Ensure that the cables match with the appropriate battery terminals.

  • Eliminate the loosely attached battery wires from their respective terminals.

Fixing a loose wire and battery connection:

Here are a couple of approaches to fix an unfastened wire problem:

  • First, fasten a slacked battery cable at the terminals onto the bolt using a screwdriver.
  • Buy some new terminals to replace the damaged terminals.

Fixing an overcharge condition:

An inaccurate ground wiring error will lead to an overloaded battery. In case of an overcharging problem, ensure you follow the following steps to diagnose the improper ground wiring;

  • Firstly, disconnect the yellow wire connection from the voltmeter.
  • Inspect the voltage reading using a voltmeter while disconnected. The reading should peak at 12v and decrease gradually, as the circuit is incomplete.
  • If the yellow line is unplugged while the automobile is running, it is definite proof of a ground short circuit.
  • To solve the problem, trace grey ground wiring to ensure that they are in no way linked to the car club frame or any other metal.

2. A weak or rapidly draining club car batteryA weak or rapidly draining club car battery

A fully charged club car battery should provide a range of 30 miles with a 36-volt battery design and 40-45 miles with a 48-volt battery combination. Due to low voltage, the fuel pump delivers fuel to the combustion engine at a reduced rate, resulting in a gradual acceleration of the car.

How to determine the output voltage of your car battery:

Checking the output power of your battery should be a daily occurrence, which can be done using a Multimeter or a Voltmeter. Below are several simple steps to test the voltage output of your battery.

  • Maintain a full charge on your battery
  • Ensure you adjust the multimeter so that it reads between 0 and 20 direct current volts.
  • Connect the multimeter’s positive end to the battery’s positive terminal and the multimeter’s negative terminal to the battery’s negative terminal.
  • Confirm the reading on the linked meter while the engine starts.
  • Repeat these processes until depending on the number of batteries in the battery cabinet.
  • Calculate the normal battery’s voltage by multiplying the total number of holes in the cabinet by two.

When the voltage reading falls below the standard reading, this could indicate that the charging system’s performance has deteriorated and requires attention.

Other possible causes include the following;

  • An undercharged alternator
  • Expired battery
  • Incorrect or faulty circuit connection

How to correct low battery voltage?

A low-voltage battery will require a recharge boost. Here is how to go about the process;

Step 1: Boosting the batteries in your club car requires one to charge a single 12V or a pair of 6V batteries connected in series using a standard charger. 

Step 2: Connect the car charger’s lead terminals to the appropriate terminals on the particular car battery. If you are supposed to charge two batteries connected in series, ensure you connect the charger to the positive terminal of one battery and the negative terminal of the other battery.

Step 3: Charge for approximately half an hour or less. This procedure should have restored your club vehicle battery to its normal operating voltage.

Step 4: For the other remaining batteries in the compartment, repeat the above procedure.  

Step 5: It is recommendable that one should use the club car charger to charge the batteries.

It is important to note that the batteries should not be left alone when performing this procedure. Also, ensure that you remove the negative cable of the pack for the proper functioning of the charging system

3. Club car plug and charger issuesClub car plug and charger issues

Select a battery charger and socket type compatible with your model of club automobile, which could either be automatic or manual. Users can consult the car’s guidebook to determine the correct type to purchase.

Following your selection of the appropriate charger and plug type, the following are the three most typical reasons for your battery failing to charge;

a) Dimensions of a stopwatch or any other timer being used

The timer usually has a fixed knob used to turn ON or OFF the charger and programming it. A malfunctioning timer unit will prevent the charger from completing the charging process at the specified time. When a charger operates continuously, it diminishes the battery’s average life.

b) Diodes  

Diodes present in the charger convert AC to direct current, enabling the current to be stored in the vehicle’s battery. However, a bad diode prevents current from flowing from the battery charger to the battery itself, and hence they should be replaced immediately.

c) A spoilt DC Plug

The DC plug transmits Direct Current to the battery via the charger. A faulty plug usually has a melted appearance, and once identified, it should be replaced immediately to avoid further battery damages.


There are numerous causes of club car charging problems, as outlined above. Other common causes could include broken fuses, defective transformers, or failed voltage controllers. In addition, you can sometimes notice an abnormal sound after plugging in your charger.

Such issues should be eliminated immediately for a great performance of the battery charger. From this article, find various troubleshooting tips for different problems with the charger. If the process appears challenging, ensure you consult an expert on how to get rid of the problems.
