Check the connections to see if there is something loose. Maybe just reseating the connections will help.
Have you always manually overridden the charge wizard to boost mode over the last three years of travel when connecting to the generator?
Do the batteries look in good shape? Water in the cells if wet cell battery. What is the voltage of the batteries before you started?
I checked the instructions. The Charge Wizard should switch to auto mode if on boost when the batteries have reached sufficient charge. I would assume it would switch to lower voltage and amps not try to start again in Boost. Maybe the unit Charge Wizard confused. Maybe disconnecting the batteries for a few minutes will reset it. If you purchased from BestConverter give them a call.
The manual button has been provided to allow the operator to temporarily override the con-verter (not recommended) or to verify the converter is operating properly. For manual operation, Press and Hold the button. The indicator light will soon remain “ON” indicating Boost Mode. Continue to hold the button and the light will blink rapidly indicating the converter is in the Normal Mode. Continue to hold the button until the light blinks slowly indicating the con-verter is now in the Storage Mode. After the manual button is released the converter will stay in the selected mode. When the battery charge status changes, the converter will return to the automatic mode of operation to prevent damage to the battery.
