Fleetwood Fiesta Electrical Problems

In our 2010 Fleetwood Fiesta 34B our house batteries are not being charged by the shore power and electrical power slowly fades until we turn on the engine, then the fans/AC work, lights brightened etc. I am told our converter is to blame, looked at the schematics that said the converter should be somewhere between the sink and stove but it isn't. The inverter is. What is the difference between a converter and an inverter?

I don't really understand electricity..why doesn't the shore power maintain all our interior utilities like TV, AC, lights, electrical outlets..aren't they all 120? At present we have a charger on 24/7 to the house batteries but it doesn't really do the job.

    CONverter changes 120VAC to 12VDC
    INverter changes 12VDC to 120VAC
    With no noise inside you should hear the fan running. Also the converter might be behind the breakers. No DC voltage could mean bad battery, bad converter, blown fuse or several other things. To check anything you really need a volt meter and understand how to use it. Volt meters can be had lots of places for under 25 dollars.

    A converter takes 120 volts AC to 12 volts DC. An inverter takes 12 volts DC to 120 volts AC in either a modified sine wave (a square shape) or pure sine wave (like what is in your S&B).
    As for your house batteries not charging, I too would say that it is a bad converter.
