Chasing my Tail...Electrical issue

[wintertree]

Greetings all...our RW now has only a couple of plugs that work....the ones in the washer dryer area....and under the bed.....all other plugs in the trailer have no power....checked everywhere.....thought of GFI issues....
Is the Plug in the bathroom the only GFI plug with Test / reset control ?.....checked the wires going to this plug....no power.....power to the fridge (AC.... we have an RV fridge)....no micro...no tv.....no fireplace.....
Checked in the back corner where that crappy ...problematic Moldex plug is located....no power going into or out of plug....checked the pedestal...(we are on a 30 amp service here)...plug not great....and we do have some AC power in the trailer...
My wife got carried away with cooking and ran way to many things when it went out....That might be the clue needed to solve?....Breakers are fine...
I am frustrated now and need a break....any thoughts...?

If your coach came with a generator prewire, there will be a transfer switch above the generator cavity that switches between shore power and generator. This transfer switch has been a problem for some on this forum. The other possibility is that one of the connections on the back of the shore power plug has come loose or burned off. Find someone with a good quality voltmeter to measure if you have 120 to neutral available at the input of the load center in the entry closet. Good luck.

try funning one AC unit at a time. If you find that only one will run then you have a clue that you only have power on one of the two bus bars on the panel in the coach. Do you have a generator or generator prep or a power cord reel ? Those are them most likely issues in the coach that can cause no power to 1/2 of the coach. If the outlet in the park is wired wrong and the hot and white wire are reversed (very dangerous) this could also cause the problem or possible your 50 amp to 30 amp adapter or 50 amp power cord has a bad wire connection.

I would suggest you get yourself a Hughes watchdog with EMS , using one of these will keep your trailer safe from miss wired park problems and it tell you what your voltage is going to the RV and real time power usage by blue tooth and a cell phone app that you and your wife can use to manage power when your on a 30 service

Just a follow up...Thankyou for the suggestions....I woke up with a new attitude and prepared to do a little more testing before actually replacing things...
To my delight I found the reset breaker on the Magnum inverter had popped...most probably the charging system was struggling to operate properly with the overload on that leg of the shore power....from too many things going on in the kitchen (we are presently only on 30 amps)....The inverter is mounted on the back wall slightly behind the genset enclosure...I noticed the breaker button had popped when I climbed in there to have a closer look at the transfer switch...
Thanks again !!

The inverter shouldn't have anything to do with the microwave or fireplace. In your vintage coach the fridge circuit should be on the same circuit as the pantry, outlet by the stove, and the entertainment center. The microwave and fireplace should each be on a separate breaker.

Our inverter (3000 watt magnum) is installed to run all of our RW....We do have an extensive battery bank.....and do not have a Res. fridge....

Then you don't have an inverter, you have a converter.
Inverter uses 12 volt from your batteries to produce 120 volts usually to a dedicated plug such as a residential fridge if equipped.
Converter uses 120 volts to provide 12 volts for lighting, slides, jacks, fridge/water heater controls & charges your batteries.

Thanks for the lesson....Our magnum "Inverter" powers our ac circuits....what we were having problems with..

[travelin' texans]

You apparently have a HUGE bank of batteries, a roof full of solar + a good generator to be able to run your acs from an inverter & keep ALL those batteries charged.

The previous owner of our RW ...set the trailer up to be temporarily self sufficient when traveling between full hook up sites....his wife needed special care most of the time....he installed a genset....large inverter....4 high capacity 6 volt batteries(house bank) and opted for the gas/electric fridge..
As time progressed he decided she needed more care...traded the RW in on a loaded "A" class so she could use the facilities while traveling..
Last time I heard(pre-covid) they were still on the move....trying to see as much of the country before she progressed in her illness to the point of needing sticks and bricks
