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.

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.

CONverter changes 120VAC to 12VDCINverter changes 12VDC to 120VACWith 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.

Well what runs hte AC\/C. lights etc why isn't the shore power doing it directly? is the interior AC or DC I don't know anything about electricity

Your rig could be equipped with an inverter/charger and no converter. Look at the inverter and post make and model.You may need 12 volts DC control to operate the AC unit.

I had the same problem with my fiesta. Had to replace my converter. Mines was located in the bathroom behind the vent.Wfco junk.

The converters are usually close to the battery compartment. If you have a grill under your ref. remove it and look inside. the converter may be covered with loose wire looms and hard to see.

Plug your coach into 120VAC in a very quiet location and listen for a humming sound.

Two places I would look is under your front steps and BEHIND the 110VAC power panel.......Dennis

No, I am not sure. I have an older Terra pamphlet that has the 34B floor plan.
It would not be behind paneling.
I have seen some in the upper cabinets and in closets.
Just guessing!

Well there is no room in the head and the wall under the TV is solid, don't intend to rip up panelling. Not under the fridge as there is no cabinate, sure you are looking at our RV?

You might be a candidate for a visit to a service center.

It would not normally be in a slide.
Floor plan of the 34B that I have a copy of would indicate that it could be in the head or under the Big TV on the head's front wall, or in the bedroom on the head's rear wall.
It could be in the cabinet below the fridge

They are in different locations based on year and model.
As posted earlier it could be under the refer door, under a dinette under a bed. It should be inside the rig in fairly close proximity of where the shore power cord enters the rig.
