I want to hook up an 2000w inverter. I need to know where and which circuit is for battery charger so I can shut it off while inverter is on. Also, where is the charger on my 2003 adventurer located.? I can' seem to find it. On my circuit panel, one circuit is marked fridge/ converter. But there's only one wire to it. Is the converterbreaker marked differently? Any help would be appreciated. Thank you
