Electric switching problem

[StillNoTV]

Hello,
I hope this is in the correct place to post this. I am new to the RV, so far loving it and all the great people we meet after our first trip. Here is my problem. This is a new motor coach to me. We knew this was a problem and are now trying to find out how to fix it.

2002 Fleetwood Revolution

Problem: Shore Line connected all outlets work and everything is fine.
Shore Line disconnected, all outlets in bedroom and kitchen do not work.

Checked: Checked Inverter and it is putting out 120v to Microwave and AC Circuit 1 (the living room area plugs are working when shore line is disconnected).

Talked with Fleetwood and they told me that the plugs should all be on and the refrigerator should be off.

Does anyone have a starting point?

Hello and . We are glad to have you join us here and we look forward to reading of your adventures and experiences. I am sure you will enjoy the website and forums.
Check to be sure all electrical connections in the inverter and distribution panel(s) are tight. If the inverter is passing through current to these loads but not powering these same loads, there is a problem in the inverter. Check circuit breakers on inverter first but they should be good for pass through to happen. Might give inverter a rap to see if a relay is stuck. Good luck and keep us posted.

Thanks RV Wizard, the people and places this summer have been great.

At the Inverter I see 120v, but at the circuit breaker under the bed labeled Inverter I do not see power. It looks like the power is going through the EMS circuit board before it gets to the inverter breaker. There are relays on the circuit board on the EMS panel. Do they only work when the EMS is on shore power? Is there a another relay that could be stuck and if so where is it?

One circuit breaker under the bed (30A?) feeds power TO the inverter/charger when shore power or generator is running. That supplies both charging and the branch circuits when external power is available. In addition, there should be 2 or 3 15 amp circuit breakers in a separate panel that handle the inverter output to the branch circuits (outlets).

Check the GFI recepticals, one may be tripped. Best to trip and reset them to make sure.

I have triped the GFCI (I have two).
So the circuit breaker that is marked inverter will only have power when the shore power is pluged in?
The only other breaker I can find are on the inverter itself. It seem like a switching problem to me but I can not find any relays but the one the EMS system has. It is driving me crazy why does it work with shore power but not with the inverter?
Thanks for the help, I am open to all suggestions.

Sorry Gary do you know where they might be hinding?

If you have the owner manual for the inverter, you might want to refer to it as it may explain in a manner better than I have tried to do. If you have power at these loads on shore power through the inverter, you should have power to these loads when the inverter is making power; provided all the internal components of the inverter are working correctly. What model is the inverter?

[Gary RVRoamer]

Your inverter is also a charger and converter, so when shore power is available it normally receives power (30A) from a breaker on the main load center. This power is passed though the inverter to feed the output circuits as well.

When shore power goes away, the inverter's internal transfer switch shifts to inverter mode and the inverter draws power from the batteries to make 120vac for the output circuits. In either case, the power passes though an internal circuit breaker in the inverter, and there should be a reset switch(es) on the inverter for that.

The output wires from the inverter normally go to external circuit breakers that protect the individual circuits, e.g. microwave, accessory outlets, etc. Those would typically be placed in a separate breaker box, but a lot depends on the layout of the coach & its wiring. Mine is right next to the main breaker panel, but yours???
