The 05 fault code is low battery voltage, I do not recognize the OL. Since your coach batteries appear to be fully charged and everything works on generator, you apparently have an issue between the coach batteries and the coach. The wire from the coach batteries runs thru the 50 amp breaker in the battery box, thru the Use/Store switch to the converter and then to the individual breakers. The generator is hooked to the converter and then to the breakers. Since that system works, you probable have a problem in the wiring from the batteries to the converter. If you have a volt meter, you could check and see if you have power on the side of the 50 amp breaker between the breaker and the Use/store switch. If you have power there, the breaker is good. Next check if you have power on the other side of the Use/Store switch. If you do, then that switch is good. Then you have to check the converter and see if power comes out of there to the individual breakers. The problem probably is in one of those three: 50 amp breaker, use/store switch, converter. Do all this with the generator off and not plugged in to shore power.
