      Jacqueline HernandezAug 28, 2025
      A series of flashes on your NOCO Genius Remote Starter can indicate several issues: a short circuit on the battery clamps. In this case, remove all loads and reconnect the clamps to the battery. It can also mean that a high voltage was detected at the clamps (the GBX75 is connected to a voltage system greater than 12V, such as 24V), a bad battery cell was detected, a charge timeout error occurred (i.e. the GBX75 has been in bulk charge for too long), or back-charge was detected into the GBX75 through the clamps while in Boost Mode (i.e. the GBX75 is in Manual Override and then connected to a system greater than 12V, such as 24V).
