This is on the front lower end panel, curb side on my '60 Airstream Overlander. It is wired to an Orange 12V wire inside. Can anyone tell me how it was used and what it was used for? At first I thought it was to connect the battery that is in a battery box just adjacent in the front, but I don't think so as there is another orange wire on the exterior that seemingly is for the battery connection with the negative grounded.  |

This is a wild guess, so don't trust me, but I'd a say it's probably for a generator. Is there another outlet for the a 30amp plug to get power from the campground box?

Susie, I was going to guess generator also, because it resembles a modern generator plugin. However, a generator plug that shape has four slots rather than three. The warning plate specifically refers to battery voltage and polarity. I wonder if the modern 1960 application would have been used for an external input (car alternator via a harness plug perhaps) to recharge the battery onboard. Just a W.A.G. though....

Yes, the 30A "shore power" outlet is on the streetside and is(was) wired into the main 110V panel.
This one was definitely a 12V outlet as it was wired into the tow cable circuitry.
Only two connections were connected when I removed it from the exterior and then when I removed the inner panels to access the tow harness connections (there was no junction box accessible) so that I could rewire for a modern 7 pin cord, there was no additional wiring at this location.

My guess it is set up to use in a marina where they would of had battery voltage shorelines. the plug appears to be a standard 3 point twist lock plug of an early nature. Many battery voltage shorelines used that type plug. Battery voltage was much safer than AC in the days before ground fault interrupters around water.

Big Bill,
That makes sense here in Santa Barbara.
Fun history with this trailer...
I bought it 15 years ago from one of the twin daughters that were the original owners. Their father, upon their high school graduation, bought them this trailer and a truck to tow it with and told them to travel the US for at least a year. They did! I am still trying to get more history, but know that one of the sisters kept it in a trailer park here in town that she also managed for many years.
I'll see if I can find out if they ever kept it at our local harbor and used this shore power you mention.

If she bought it new does she have all the owners manuals? They might shed some light on it. Another thought is it may have been used for a quick charge by having a cord that went to there truck battery, without having to hook up the tow plug. Might have used it when staying in the same camp for multiple days. Hope she remembers or knows.
