Welcome to the world of Vintage Overlanders!

I am assuming, the cause of the short is corrosion but I would like to avoid dismantling everything to follow the cord through the trailer. Thanks!
I am not certain, but do believe that Airstream was still utilizing a junction box for the unbilical cord located in the bellypan of the coach in 1966
(my '64 Overlander has this as does my '78 Minuest). This junction box was usually located in the front curbside corner of the bellypan and could be identified by a square/rectangular aluminum "hatch" attached with either pop rivets or sheet metal screws. Something else that might warrant checking out is the Bargman connector itself . . . the most frequent source of "short" problems for me was the blade-type Bargman RV connector . . . it was an annual chore to disassemble the connector and clean corrossion from all of the contacts.
Good luck with your investigation!
