6 EZ GO Charger Fault Codes [Explained by Expert]

Flashing red lights indicate an issue with your EZ-GO charger. There are multiple error codes that can help you to identify them. The problem can occur due to low battery voltage, high battery temperature, charger firmware, malfunctioned wiring, damaged batteries, excessive current flow, etc. 

To fix the issue  – 

• Identify and remember the lights flashing pattern.
• Match the pattern with EZ-GO charger fault codes.
• Take proper steps to fix that problem.
• Disconnect the charger and restart the charging.

While identifying the pattern, make sure to count the red light flashes correctly. 

There are six different EZ GO Charger Fault Codes. Let’s explore what they mean and ways to fix them.

1. One continuous Red light

One steady red light indicates something wrong with the charging voltage. Charging with the incorrect AC voltage can be the reason. 

Note: You have to charge your EZ GO batteries with 100-120V AC, which is standard for most States of the US. 

Cable problems, electric outlets, and circuit breaker problems can also cause this issue.  

How to Fix?

➣ First, ensure you are charging with the correct charger.

➣ Charge with proper AC voltage. 100-120V AC is the standard voltage for charging your EZ-GO battery.

➣ Inspect the charger cord.

➣ Fix any problem with the electric port and circuit breaker.

2. One red flash and pause repeat.

When the charger flashes the red light once and then pauses and repeats, this error can indicate two issues. The first can be a loose connection or dirt in the charger connector. The second issue can be unsuitable battery temperature for charging. 

EZ-GO charger will stop charging when the battery charge is more than 50 degrees C or less than -10 degrees C.

How to Fix?

➣  Connected the charger properly and make sure everything is fit and tight.

➣ Remove the charger and check for dirt or anything else in the connectors.

➣ Clean dirt and debris in the charger connector.

➣ Sometimes, you may not see the dirt, but cleaning it may fix the error.

➣ Unsuitable battery temperature causes one red flash. To fix it, disconnect the charger and try understanding the battery temperature.

➣ Let the battery reach the proper temperature for charging.

Expert tip: Always check the battery temperature before you start charging. 

3. Two frequent red flashes and pauses, then repeat

Two red flashes and a pause indicate that the battery is not within the suitable voltage range required for charging. 

When the battery pack charge exceeds 36 Volts, it will not charge and show an error. On the other hand, if the battery pack has over 67.2-volt charge, it will also show the error. 

How to Fix?

➣ Use a multimeter and check the battery’s voltage. It should be between 36 volts and 67.2 volts. 

➣ If the battery pack has more than 67.2 volts, let the battery discharge naturally.

➣ Battery volt less than 36 indicates it’s too dead to charge. Check the manual for ways to charge an over-discharged battery.

➣ Sometimes, the battery pack may have correct voltage, but still, causes the error. In this case, there might be a problem with individual batteries within the battery pack.

4. Three frequent red flashes and pauses, then repeat

Three consecutive red flashes and pause errors indicate charging timeout. That means the battery is taking more time than it should. This problem generally occurs when there is an issue with the battery pack or charging system. 

High ambient temperature can also cause this problem. That means that the surrounding is too hot for charging.

How to Fix?

➣ Monitor the charging time. You can restart the charging after some time.

➣ If the error happens again, check for any issue with the battery pack.

➣ Make sure the batteries are adequately connected correctly within the pack.

➣ Charge the battery at room temperature.

➣ Ensure the charger is well-connected and clean.

5. Four frequent red flashes and pauses, then repeat.

Four red flashes and pauses indicate the battery pack is entirely dead or discharged. It can also indicate that a battery within the pack is dead or faulty. The connection between the battery pack can also cause four red flash issues. Lastly, the battery charger can also be faulty.

How to Fix?

➣ Check for any visible problems in the connections of the battery pack.

➣ Inspect the voltmeter to find out if there is a dead battery within the pack.

➣ You will need to charge dead batteries individually.

6. Six frequent red flashes and pause, then repeat

Six red flashes can indicate some internal issues with the charger. Which means the charger needs replacement or professional servicing. 

Sometimes, this error can appear for no reason, and restarting the charging will fix the issue.

How to Fix?

➣ Unplug the charger from the DC and start the charging again.

➣ If the same error appears, take steps to fix its internal issue.

Advice: Charge the battery fully before storing your golf cart for a long time. It will keep your battery healthy.

Final Takeaways

Before leaving, let’s recap the key points of EZ GO charger fault codes.

• Identify and count the light flash correctly.
• Find out the problem according to the error code.
• Sometimes, error codes can appear due to internal glitches and without any issues. Restarting charging can solve that.
• Maintaining battery voltage, battery pack connection, and charging at a suitable battery temperature can solve several errors.
