Iím a novice (you know nothing Jon Snow) owner of a 1960
Overlander Land Yacht. Originally, the point was to find a trailer of any brand to remodel. I didnít yet know the magic of airstreams. I certainly never intended to completely renovate a trailer. But one mysterious Facebook market place ad later and poof, Iím an airstream Junkie. (The owner had taken down the posting a month ago and it was deleted, she double checked. Some things are meant to be.) Needless to reiterate the common knowledge that each older airstream is a bottomless pit of more projects to complete. Itís been an adventure of learning. Electrical however, hahaha...HA!... is just laughing at me. The more I learn the more I realize I am clueless.
So hereís a basic run down of where I am at right meow!
I finally figured out:
1. How to check the continuity of the wires. Most everything had already been dismantled. So I had to take 26í of stranded wire, splice it to the wires throughout and use that as the negative conductor to check with the multimeter. Score!! Most of them work!
2. You have a better chance of finding detailed pictures or the Lochness monster than a 1960
electrical diagram of the OG system. Why? Because Airstream didnít make manuals until 1964
.... but has no one else made one as they updated their own? Hmm? Is it really that elusive?
Wait! Found it!!!
3. Airstream most likely used romex in the early 1960s. Just after that they began using ďtwo strandedĒ. They didnít use ground wire in either application. This was made obvious by the two prong outlets. (Do I sound like I know anything about anything yet? Smoke and mirrors folks!) They would ground receptacles straight to the aluminum cutout. Not to the frame. My airstream, which will be hence forth be refereed to as Nessie, had 12g two stranded wiring. Along with random wiring throughout.
(What is the crank for? Is that to control the awning?)
Except the shore power clearly has a ground. Where did it go to panel? And then just stopped?
Iíll ask about other random wiring throughout below.
3. Airstreams used a Univolt system... which should also be called the magic pixie dust system. Here is where my confusion(s) begins to set in. What is the Univolt? Was it the converter with a built in surge protector?
Let the questions begin.... again.
I intend on adding ground wire to the two stranded wiring. I believe the wiring must have been updated because I donít see any romex at all. I bought bare 12g solid copper.
1. Does the ground wire need to be the same gauge as the two stranded already in place?
2 If I run the ground wire along the two stranded, will it be safe since it runs through insulation?
3. Why would romex not be safe in an airstream?
4. What should I use to secure the wiring in place? Currently itís taped onto the aluminum exterior panels. (With ground wire seems like there would be no point.
5. Should I be adding ground at all? Or does it work to ground it to the panels since they are aluminum and attached tot he frame?
I will add grommets any place the wires pass through the aluminum. I am of course going to be replacing the electrical outlets to three prongs.
Trailer lights electrical:
Iíll attach a picture. Iím lost in the sauce.
Half of the multitude of red wires I traced to the back lights.
1. So what are the rest of the wires too?
2. Does anyone know about the 1960
brake system? Where does the electrical run? I know there is some wiring under the sub floor. Which is only half exposed because the other half was in great condition.
Do you like the knots? They are custom...
There is what looks like romex under the subfloor. For what I assume to be breaks. One yellow, one green.
On that note.... what is happening here? Is that a splice?
Any and all help would be immensely appreciated.
