Ok... Plug your RV into a 110 source (shore power) and try the electrical outlets. If you are not getting power to your outlets then your inverter is the problem (fuses, bad connection, etc). If they work then start your generator and plug something directly into the generator. If it works then the connection from your generator to your RV is the problem. If it doesn't work it is your generator which could be something simple or something not so simple as a bad magneto.
