Where are the output breakers on the inverter?
My friend has a 2010 Triple E Class A motorhome That has no power going to several of the outlets. I checked the very minimal wiring diagram that came with the coach and determined that there are 2 AC output legs coming out of the inverter , one supplies power to the microwave which still works, the other supply power to a kitchen plug, the bathroom plug, the entertainment unit and a couple of others .There is no power on this leg. We could only find 2 plugs on this circuit that have GFI. These won't reset so I pulled them out and there is no power coming to them. There is a 30 amp breaker sending shorepower to the inverter and it has power going through. Checked everywhere for another Gfi plug, in the bays , outside , everywhere there in none that are not on this circuit. Can't find any breakers on or near the inverter. What next? I have spent several hours at his RV site trying to help him out.

I haven't looked at mine recently but aren't there reset buttons on the inverter itself?

Check the patio outlet(s) too.
I've seen wire nuts just fall off and open circuit, hot wires pop out of outlet clamps, and screws on breakers not tightened down. All problems from the factory. One of my problems occurred because they'd used too small wire nuts that fell off and open circuited...inside the transfer switch box.
Without being there to look at the rig, it's a little hard to figure out his particular problem. I understand from my reading that there are usually two AC breakers on the inverter itself. These may be 1/4" diameter round rather then the traditional bat handle breakers you find in the breaker panel.

I forgot to mention that my friend apparently overloaded this circuit with a toaster and a coffee pot. He said it went out just as if a breaker popped.

Have you looked at the Magnum website. You can browse or download manuals and diagrams they may help isolate your friends problem.

There are reset buttons on the side of the inverter for output AC.

about a 99% chance he blew the GFI outlet in the bathroom.LOOK and FIND a outlet plugin with GFI reset and that most likely is your trouble.Like i said usually in the bathroom.That being said there are
reset buttons on most inverters but most likely GFI is blown somewhere

Also, some Magnum models do not have the output breakers, only the input breaker. If your breakers are not popped you may need to do an Inverter Reset to get things running again. You can get good technical information at the Magnum Energy web site. That depends on the model you have, but the breakers are white push buttons on the left side, toward the rear if looking at it with power up front.

Ahh, that sounds like a loose contact or something similar. If there is a poor contact somewhere in the string, and it's stressed by an overload, it can open circuit.
I'd start by trying to get a sense of how they wired the rig, measuring voltage as I went along, remove vent grills and the like, remove outlets and inspecting.
Much of my wiring is NOT in the walls, it's hidden under false floors in the cabinets. Including overhead cabinets. They hide the wiring under kitchen cabinets too. And under the refer. Look for loose wire nuts or wire clamps and screws.
