The inverter is showing Error code E05 OL, which is an overload error. When plugged to shore power the error does not come on and utility light is green. If I unplug shore and start engine the error comes back, the only thing hooked to the inverter is the residential fridge which wont come on with the inverter. The inverter is supposed to run the the fridge when I am driving. Any ideas on whats going on or how to reset the inverter?.....thanks Mark
