Camper a/c not working

Yes it is my air conditioner, im not sure of the a/c model without looking at the manual, but it is a 27' bumper pull. I apologize i should have been specific, but when i said that i tested wiring i meant that i tested with a meter. If i'm understanding you correctly, your saying that the breaker for the 20 amp dedicated to the air conditioner should be tied into the convertor? You'll have to excuse my terminology on electricity because i dont know it well at all, but i dont see why it would tie into the convertor if the air conditioner wasn't ran through the convertor? If that is the case then im assuming the convertor going down is why the air conditioner stopped working at the same time, but dont understand why it won't work with a new convertor? I also don't remember hacing a breaker on the convertor (old or new), only fuses. Below is an attached website of the new convertor i bought ... Even though it is a hunting camp, we have electricity from a pole as we all do in our homes. Thanks so much for the help so far!
