AC power issue

Hello out camping and just lost power to the front TV outlet the one across from the sofa the outlet the ice maker plugs into and the bathroom outlet. I have checked the breaker no issue and have shut off the main breaker on turned back on and still no power to the outlets.  I believe these outlets are tied into the inverter which is original not totally sure on that I checked the breaker on that and it's on.  Any ideas what to check next?

Thanks

Try resetting the gfi breakers in bathroom or maybe kitchen?

Thanks I thought of that already none of the outlets are GFCI.

You WILL have a GFI someplace (unless a previous owner has removed it).  Agree, that is the likely suspect.

I have looked at every plug and seems I don't have a GFCI.  All the outlets seem original the reset button wouldn't be behind the faceplate would it? I'm looking for a reset on the outlet itself.

I'm looking at the 110v elec relay system wiring diagram do you think it could be the Inverter Relay box?  The reason I ask in this diagram the outlets affected are on one leg going out of this box.  Under the bed is where it's located and it says dual line manual transfer switch.

I believe you are referring to a second ATS (shore power  or inverter IN and OUT to everything that can be run on the inverter.  Not all coaches have the second ATS-- some use the inverter/charger's internal ATS.  If you have two ATS's, absolutely check inside for tight connections (all power OFF)  and then turn plug in and check for power in and out.  Then in and out from the inverter.

The GFI in the bathroom (on the right when sitting on the John) is hard to see; next to the TP and switch for the pump. It's the only one on board I know about.

I would like to post a pick of the diagram and the transfer switch but can't figure out how to do it on my Iphone.

Bottom line question:  Do you have TWO ATS's?  If so, yes the second one could be the issue and is sure worth checking.

Raise the bed to check.  Should have the answer in 10 seconds.

Shore power off, generator off, inverter off.

Well I checked all the wiring connections inside the transfer switch non seemed loose.  I didn't shut the invertor off before checking the wires Anyway turned the power back on the the breaker blew on the that operates the recepticals that were not working. Very strange the recepticals are working with the tripped breaker.  If the try to reset the breaker it immediately trips.

Is the breaker that is tripping on the main 120 VAC panel or on the sub-panel?

Look at the label--what does it say?

Yes you have a GFCI. Take a flashlight, go into the bathroom and check the outlet next to the sink. It's a brown GGCI. You can't see the  buttons without a flashlight. Best to get rid of the all brown one and put in a conventional. This was a stupid blunder on their part.

Sorry Brett I responded but not sure why it didn't post.  The breaker says bathroom, kitchen, ice maker, main TV & recepticals.

Puzzling.

The breaker says bathroom, kitchen, ice maker, main TV & recepticals.

BUT, won't those same breakers work from the inverter.

If so, would expect them to be on the sub-panel (the smaller one, NOT with the two 50 amp breakers pinned at the top).

Actually, I will PM you my phone number.  Call me.

I would open the fridge access panel and unplug the ice maker and see if that is the culprit .. does your ice maker work?

After that it gets more technical
