Are you sure you are plugging into 30 amp 120 volt and not a 240 volt receptacle?

does your shore cord have continuity at both ends? Sounds like a supply line problem But doesn't explain the lights.

Should be really close to the genny but very probably inside the rig. It will be square maybe 10 inches by 10 inches. Start with where the power line comes into the trailer and follow it. That line and the generator line will meet at the transfer switch.


You can also trace backwards from the converter.

Good luck.

I would suggest reetting the circuit breakers. Turn all breakers off applying light pressure toward off. Turn on main breaker if equipped, then branch breakers one at a time.
Next would be to remove the cover over the 120 volt circuit breakers, With shore power disconnected, check for loose connections.
If you or son is comfortable while connected to shore power, check for shore power to the panel.
Is shore power hardwireed to the rig or does it have cord body connection on the side of the rig. Common for connections pull loose in connector.

If you have a transfer switch, yes they can fail. If you have a generator and you don't have to plug your cord in some place in the RV then you probably have a transfer switch. Mine got stuck in one position, in my case no generator power. I was told to find the transfer switch and with power off to tap on the box with a small hammer or butt of a screw driver. Sure enough I had power when I went to use the generator, but next trip same issue. I was told since Toy Haulers are often in be in dusty conditions and this can be an issue. Dealer cleaned it and never had another issue.

I'm still not clear that there is power at the household outlet. Just because it used to work doesn't mean the breaker on the house panel hasn't popped or something else in the household system failed.

Always start at the source and work your way downstream:
- Start with a multimeter at the outlet and check for voltage.
- Then plug in the cord and check the far end of the cord to make sure you have voltage.
- Then trace the cables to the transfer switch (assuming there is a built in generator) and check the voltage going into the switch and coming out the other side.
- Then go to the breaker panel and check for voltage.
- Etc..

Eventually, you should find that the 120v power is no longer there and now you have a good idea of where the issue is.

Did you plug the trailer cord into a generator? Or does the trailer have a built in generator?

12 volt I’m fine . But when I plug in shore Power nothing works . No lights , nothing . Yes tested the outlet in the garage and works fine. I feel that the trailer is not switching over to 110v??
Use that same voltmeter to check voltage on the RV main breakers in the distribution panel.

Then check each connection back to the cord inlet.

Anything else is a wild guess.
