Error LED Is Illuminated or Flashing

The flashing LEDs on your charger indicates an Error Condition. The Error Conditions are handled differently between different versions of the model charger. First you need to determine which model charger you own, then you can correctly decipher the error condition.

Genius 1.0 vs Genius 2.0

 

Note: The image above depicts common differences between V1.0 and V2.0 Genius Chargers that are consistent with each model charger, not just the G750 model (shown above).

Version 1.0: Flashing LEDs.

If all the LEDs are flashing, this indicates an error condition. The Error Condition can be a low voltage battery, battery voltage is too high, possible battery short, or the battery will not hold a charge. The most common reason for all the LEDs flashing is a low voltage battery. In 12-volt  mode, any connected battery below 7-volt will create this error condition. In order to remove this error, increase the battery voltage above 7-volts. We suggest jump starting the battery if the voltage is below 7, to bring it back to a recognizable range.

Version 2.0: Understanding Advanced Diagnostics.

Advanced Diagnostics is used when displaying Error Conditions. It will display a series of blink sequences that help you identify the cause of the error and potential solutions. All Error Conditions are displayed with the Error LED and Standby LED flashing back and forth. The number of flashes between each pulse denotes a potential Error Condition (except reverse polarity and low-voltage battery).

Error

             Reason/Solution

Single Flash

Battery will not hold a charge. Have battery checked by a professional.

Double Flash

Possible battery short. Have battery checked by a professional.

Triple Flash

Battery voltage is too high for the selected charge mode. Check the battery and charge mode.

Error LED Solid Red

Reverse polarity. Reverse the battery connections.

Standby Solid Orange  

Battery voltage is too low for charge to detect or charger is in supply. Jumpstart the battery to raise the battery voltage.
