Half of the outlets have no power

So that outlet is bad, and most likely could be replaced...

My '66 was like that: all the outlets were wired from one to another. So the wires went from the outlet closest to the panel box, then went to the next closest, and so on. If a connection was bad, or is connected, all other outlets down line would also be out.

I am not sure what you mean that you bypassed the outlet or even why you would do that. If the receptacle is not good, I would just replace the receptacle. If you don't replace the outside receptacle then you will not have any power available to plug into the outside and now have to run an extension cord to an inside outlet. Just replace the outside outlet (receptacle) and fix the problem once and for all.

Well. the by pass was for testing purposes only.
Disconnecting the outlet and "bypassing" if correct the issue and it will be replaced.
Now the question is like GetOutDoors is saying: If a connection was bad, or is connected, all other outlets down line would also be out.
I'm surprised that all the outlets are in one circuit.
Why is it that in the 12V system every ceiling light-fan has its own circuit but this is not the case on the 120V?

Think as if your trailer is an 8' x 31' room. Easier to run from outlet to outlet on one side of the trailer than to break the run into two separate circuit runs of wire. Ed
