I finally have got enough time to look at my trailer and tried to find
out why electricals were [mostly] not working. I did some standard
troubleshooting tricks and found out that I have a bad ground
connection. When I cleaned up an area of the trailer with an angle
grinder and hooked up a 12v negative to that, instead of white on the
plug, the lights lit up.

This trailer uses the body of the trailer as a negative ground. I have
a feeling that it does not work well after rust sets in.

It was built like a damned Brit car, eh? That sucks. ;/

OK, what kind of cable should I use, to avoid deterioration over the
years in Illinois weather.
