How to Tell if Golf Cart Charger is Working

If you own a golf cart, you know that a reliable charger is essential for keeping your battery in top condition. However, it can be challenging to tell if your golf cart charger is working correctly. Here are some tips to help you determine if your golf cart charger is working or not:

  1. Check the charger’s LED lights: Most modern golf cart chargers have LED lights that indicate when the charger is working correctly. Typically, a green light means the charger is working correctly, while a red light means there is an issue that needs to be resolved. Check the manufacturer’s instructions to see what the LED lights mean.
  2. Check the voltage of the battery: You can use a voltmeter to check the voltage of the battery before and after you charge it. If the voltage increases after charging, it’s a good indication that the charger is working.
  3. Check the charging time: If you know the normal charging time for your golf cart battery, you can check to see if the charger is taking the expected amount of time to charge the battery. If the charging time is significantly longer than normal, there may be an issue with the charger.
  4. Listen for a humming sound: When the charger is working, you should hear a soft humming sound. If you don’t hear anything, it may be a sign that the charger is not working correctly.
  5. Check the connections: Ensure that the charger is correctly connected to both the battery and the power outlet. Loose connections may cause the charger to malfunction.
  6. Monitor the temperature: The charger and battery should not get too hot during charging. If they do, it could be a sign of an issue with the charger.
  7. Consult the manual: Always consult the manufacturer’s manual for specific instructions on how to check if your golf cart charger is working correctly. The manual will also provide information on troubleshooting any issues you may encounter.
  8. Check the state of charge indicator: Some golf cart chargers come equipped with a state of charge indicator that shows how much charge the battery currently has. If the charger is working correctly, the state of charge indicator should increase as the battery charges.
  9. Check the battery’s water level: If the battery’s water level is low, it may not charge correctly, even if the charger is working correctly. Check the water level in each cell and add distilled water if needed.
  10. Check the battery’s voltage after resting: After the battery has been charged, let it rest for a few hours before checking the voltage. If the voltage drops significantly after resting, it could be a sign of a faulty battery or charger.
  11. Use a load tester: A load tester can give you an accurate reading of the battery’s health and whether it can hold a charge. If the battery fails the load test, it may be time to replace it.
  12. Check the fuse: The charger may have a fuse that needs to be checked for continuity. If the fuse is blown, the charger will not work.
  13. Check the wiring: Inspect the wiring for any signs of damage, such as frayed or exposed wires. Damaged wiring can cause the charger to malfunction.


In summary, checking if your golf cart charger is working requires a combination of visual inspection, checking for LED lights, and using testing tools. With the above tips, you can determine if your golf cart charger is working correctly and ensure that your battery remains in good condition.
