      This flashing pattern indicates several potential issues: * A short circuit is detected on the battery clamps. Remove all loads and reconnect the clamps to the battery. * High voltage is detected at the clamps (the GBX55 is connected to a voltage system greater than 12V, such as 24V). * A bad battery cell is detected. * A charge timeout error occurred (the GBX55 has been in bulk charge for too long). * Back-Charge detected into the GBX55 through the clamps while in a Boost Mode (the GBX55 is in Manual Override and then connected to a system greater than 12V, such as 24V).
