Why is My Golf Cart Charger Flashing Red?

The battery charger on your golf cart will start flashing red due to a fault code. 2 red flashes can mean that the voltage is too low.

Different colored flashing lights denote different fault codes.

• If the red indicator light flashes and nothing happens after that, you must check if the charger is properly connected to the AC mains.
• If there is a single flash of the red indicator LED lamp in the battery charger, it indicates there is a fault in the charging mode.
• If you observe two red flashes it indicates a fault in the battery voltage.
• Three red flashes by the LED indicator is meant to convey that the battery charger has timed out.
• There can be four red flashes as well which means that it is another form of battery charger timeout.
• Six red flashes indicate that the charger is faulty.

The battery charger timeout with three flashes can be due to one of the three situations given below:

• The charge in the battery bank has gone below 50%.
• The batteries have gone old and cannot take more charge.
• The charger cord is too long that it impairs the capacity to charge properly.

Why is My Golf Cart Charger Flashing Green?

A green light flashing on the battery charger of your golf cart usually indicates the charge level of the battery. Short green flashes mean the charge level is below 80%, where long flashes mean the charge level is above 80%.

• If it is one solid green light it indicates the golf cart’s battery is fully charged to 100%.
• If the green light flashes at long intervals, it means the charge is above 80%.
• If the green light is only a short flash, then the charge level is below 80%.

 Why is My Golf Cart Charger Flashing Yellow?

The yellow light in your golf cart charger flashes when the batteries need to be charged. If you have not used your golf cart for some time and the battery charge level goes below the threshold, the yellow LED indicator starts flashing.

Once the charging starts, the flashing of the yellow light will stop. You may notice that if you keep the switch to Run, the yellow light can flash and on Tow position, it is not flashing. This is not how it should be. Reset the onboard computer (OBC) and you will find that the charging takes place whether the switch is in the Tow or Run position.

On some chargers, the flashing yellow light can mean that the charger is in the ‘abort’ mode. You can try unplugging the charger and after a gap of a few minutes, reconnect and see if the flashing yellow light stops and the charging starts.

Why is My Yamaha Golf Cart Charger Flashing Lights?

The battery charger supplied with the Yamaha golf cart has LED light indicators on it. The first one is the indicator that shows that the charger is connected to the mains and is ON. Whenever there are charging errors, the other two LED indicators will start flashing.

If you notice the red-light flashing, disconnect the charger at once and reconnect. If the flashing of the lights does not stop after this, you may have some issues with the batteries. Either change all the batteries or check individual batteries and replace the bad ones only.

Yamaha insists on charging the batteries of its golf carts only using the charger supplied with the carts and not with any other charger. Follow the manual for detailed information on the battery charger and how to use it correctly.
