If the Fault LED on your Furrion Controller is red, it could be due to several reasons: * The battery polarity might be reversed. Check the battery connection and correct it if necessary. * The PV input might be reversed. Inspect the PV input connection and correct it if needed. * The battery might be overcharged. In this case, check the condition of the battery and replace it if necessary.
