I finally got around to checking this second battery isolator....
If it is the same thing I had in my 71 dodge van, it works great.  So good,
that when I upgraded (lol) to a 74 Dodge sportsmobile I spliced it into its
wiring system along with the 2nd battery.  Very simple.  Are you sure it can
be used on a vanagon?? I seem to recall seeing them in JCWhitless and they
were specifically excluded(Volkswagen).

Funny thing is, I bought the old 71 dodge about 4 years ago from an old guy
that couldn't shift it anymore. He had camperized it fairly well (Maybe the
reason I became interested in the Westfalia solution).
I estimate he installed this diode type isolator in about 1980. He could
have installed it later too. He used it mainly to run a 12 volt fridge that
looked to be 1980's vintage.
