1966 Tradewind 12v wiring

I have a 1966 Tradewind and need the wiring diagram for the Univolt. The univolt works fine but was wired thru a marine switch to the trailer. The battery was wired seperatly with a battery charger. All of the fuses in the rear outside access were wired together. I would like to remove this connector, the marine switch and wire the univolt and battery as it was from the factory. Any help would be greatly appreciated...

RE:Univolt wiring

I have no experience with wiring, or ownership yet, but I do have a manual for my future coach: 1968 Tradewind -and it has a univolt wiring diagram. I remember seeing links to manuals on-line - I just can't remember where. I don't know if 66' and 68' are similar - If you can't find it on-line, maybe I can figure out how to scan and post it... what length and twin or double?

Many of the modifications made to the Univolt power converter were made because of problems with the Univolt. With the original configuration batteries were often overcharged and / or boiled dry if you were connected to shore power for a long time. This could be the reason your battery was isolated from the Univolt. This might be a good time for you to consider an upgrade to an Inteli- Power Convertor. I have also read about the WFCO unit as well. Check out for more information on these units.

Hi! I have a 66 Tradewind, too. I have a 66 owner's manual that includes a section on "The electrical system in your Airstream". It has the diagram for the whole trailer but not the Univolt specifically. Is this what you are looking for?
Not knowing enough to be afraid... (I know more than I did, but I did it anyway!)
