I have a skyline 1992 mobile home.suddenly all the outlets on the one wall in the living room stopped working.I have had different electricians out 2 look at the problem but they all say they need a wiring diagram.the model is Bay Springs 307C. Is there anywhere that I can find one?Thanks.

The only place to find a diagram would be the manufacturer, if they even keep them. Mobile homes and some modulars are the only places that typically provide or have diagrams. Houses typically do not go by wiring diagrams.

I have to say, an electrician that needs a diagram to troubleshoot a mobile home needs to go back to troubleshooting school.

Check your breakers to make sure none have tripped. You also may need to unscrew these outlets from the wall and check for loose connections,
If you are comfortable working with electricity. The power of course needs to be off when you do this.
Many mobile homes use very cheap "backstab" outlets that can develop loose connections easily.

MH's have a crossover block somewhere. I've seen them in closets and under the house.
