We have no electricity in 3 rooms of our double wide. We have checked the breakers and they are working and have electricity going to and from all of them. We have 5 plug things under the home that connect one side to the other for electricity. All of them are working except for 1 has no electricity going through the plug thing coming or going. How do we determine where the problem is?

If you have no electrical ability or have a multimeter to test each individual wire you may have to resort to hiring an electrician or friend who knows electricity.

Did you recently have a power outage OR a bad electrical storm? Wiring in a MH is complicated.

My husband has a volt meter and has tested the breakers... all have electricity coming and going from them.
The outlets, lights and light switches in the three rooms (2 bedrooms with bathroom in the middle)dont work. The meter thing he is using shows no electric to any of the switches, lights or outlets. We think we have narrowed it down to one breaker but we are still stumped since power is leaving all the breakers but the power in those three rooms still have nothing. We are at a lose as to figure out where the problem is. Any help would be greatly appreciated.
Also this whole problem started when our son plugged in a treadmill in his room (one of them without electricity now). Those 3 rooms went off and haven't worked every since.

If the power went off, you either tripped a breaker, burned a breaker out or burned a wire or connector.

No tripped breaker and breaker shows power coming from it when my husband uses his tester.
How do we determine if a wire or connector is burned out? All the outlets, lights and switches show no power at all. But the breaker says power is leaving it.

The problem most likely is a loose connection at one of the receptacles, usually the last one that is working on the circuit.

The receptacles need to be pulled out so each connection can be checked.

The power is leaving the breaker but is being stopped before it gets to an outlet. Putting a motor load on a small wire circuit, particularly if the outlets are back wired can cause a wire to burn out at the outlet. As TK suggests, pull the outlets and start looking for a burned or disconnected wire.

Ok we changed all the outlets and light switches... still nothing. My husband checked the light fixtures and no burned or lose wires. What are we doing wrong or missing?

There is little reason to change everything is you are not getting power. You first need to find out where the power stops. Maybe one of the transfer plugs has a broken lead. I've seen cases where squirrels have chewed them.

Since you have a double wide is your electrical panel in the same half of the house that has the 3 rooms with no power or is the panel in the other half? If it is in the other half you power in the connections under the house should be coming from that direction. You will need to trace the wire of the connection that you said did not have any power back towards the panel the best you can to determine where it goes. This should help you find the problem. Also check any outside gfi recepts to see if any are tripped. The 3 rooms should not be connected to one but I have encountered it before.

Do you live in south Florida?
I would plug in an extension cord in a known working outlet and take it to one of your bad outlets and measure voltage between the outlets hot and the cords neutral/ground to determine if you lost the neutral or hot, changing everything may have created additional problems? hopefully not, check all the neutral at the panel.
The problem could be in a light fixture, I would check things between the panel and the first bad recepticles/switch/light.
Good Luck

We are having the same issue in our double wide that started exactly the same. We used an outlet outside for a power tool and the electric quit there and the over head lights in two rooms and outlets in 4 rooms. No breaker was tripped, thought it must be a bad breaker so changed it out. No such luck. Have pulled out and looked at all wire connections in the problem outlets and the problem lights. Have found no burnt wires or loose connections. Did you ever find the solution to this. Would be very helpful to know.

valdess1977... no we haven't found the problem yet. Have checked breakers... they are all good... all show electricity going out of them. We have changed all plug ins, have checked everything for loose or burnt wires and have found nothing. Guess we are going to have to cut through the insulation and see where the wires go and see if we are missing something under the home.
Hope you can find out what is wrong with yours. I know how big of a pain it is to not have electricity where you need it and having to run and extension cord until you figure it out... it's a pain.

UPDATE EXPERTS please read... thanks
Also to all the electrical experts. An electrician backfed the line in the problem areas and the electrical all worked... so what does that mean? Does anyone know how to fix the problem? He was suppose to come back but things are going on with him and his family and who knows when that will be.

He bypassed the problem and got your dead outlets working, temporarily.

There is still a loose connection someplace, obviously not in any of the boxes you have checked. There can be a junction box where the two halves join, the matter is locating it to do a permanent repair.
