How to Determine Flashing Lights on My Delta Q QE Ezgo Battery Charger
We get calls quite frequently on the issue of the LEd indicator light on the OEM Ezgo golf cart battery chargers manufactured by Delta Q Technologies. We will go into some specifics here to basically cover what each color light represents and any combination of flashes with the respective color light. The visual LED display is great for charger status at a glance.
The Delta Q QE EZGO Golf Cart Battery Charger LED Charge Indicator Light will do several things depending on the situation and charger status in the charge cycle.
1.) A Short Green Flash = The golf cart is less than 80% charged.
2.) A Long Green Flash = The golf cart is more than 80% charged.
3.) Solid Green = The golf cart is 100% charged.
4.) Red Flash = fault Code.
Delta Q QE EZGO Golf Cart Battery Charger LED Charge Indicator Fault Code Information
LED Fault Codes
1.)Flash Red – Light comes on briefly but nothing after that. Check for valid AC Power going to the golf cart battery charger
2.)One Red Flash = Charge enabled fault. Check for poor contact in the DC side connector. (Check the plug position in the cart side receptacle to ensure good contact. ( Or can be a battery temperature issue or fault. Battery Temperature could be greater than 122 degrees Fahrenheit or 50 degrees Celsius.
3.)Two Red Flashes = Battery Voltage Fault. This can be from to much voltage or not enough. If the golf carts battery bank is less than 36.0 volts or more than 67.2 volts. Usually always because the battery bank voltage is to low and the battery charger does not sense enough voltage to kick on and start to apply voltage and amperage. (See my article about – How to get your golf cart battery charger to charge dead batteries.)
4.)Three Red Flashes = Battery Charger Timeout. Means the charge time was exceeded. This could be any combination of things…
a.)The Battery bank was severely depleted over 50% D.O.D. ” Depth of Discharge ”
b.)May indicate batteries are old (Sulfation/ build-up on lead plates does not allow amperage and voltage to pass thru freely causing excessive resistance hence generating heat. ( Might need to replace batteries.)
c.)Charger output current severely reduced due to excessive length of AC electric extension cord used to reach AC power source or high ambient temperatures.
5.)Four Red Flashes = Battery Charger Timeout. This means the charge time exceeded the safe parameters and operation of battery charger set by the golf cart battery charger manufacturer. Indicating a problem with the battery bank voltage not attaining the required nominal voltage level required to shut the charger off within the maximum time allowed.
6.)Six Red Flashes = Charger Fault: Internal fault has been detected. Try to disconnect AC and DC connectors from cart and Wall socket. Wait a few minutes say 10 minutes to be sure. Reconnect Ac power first then DC connector to golf cart. If fault 6 is again displayed after unplugging and then plugging in the DC power cord the charger will need to be replaced or should be brought into a qualifies service center.
