Get rid of the parts replacer and find a technician.
I assume you paid this idiot? What a wonderful way to make money. They have NO idea what they are doing and they get paid to replace parts. You paid labor and Parts Mark up. How much did you pay him? When was the last time you checked the Battery Water before you replaced the Battery? Full 24/7 hook ups, you must check the water weekly. Even a BAD Battery, the Power Converter would still supply 12 volt power. UNLESS, the Power Converter is Bad. What you need to do is, Disconnect and get your Trailer to a regular good RV shop. Otherwise you will continue to pay for worthless help. You have so many symptoms and problems and your tech knowledge is very limited so help from us would be a waste of time.
