Thanks for the reply, Allan. I appreciate your time and expertise!
The switch itself is properly wired, and I even added the jumper
wires for the point rails like you suggested. And I understand which
polarity needs to power the frogs per postion of the two sets of
points. The real question I have is control. How do I control the 3
seperate frogs to provide the correct polarity for the 4 possible
track positions?
I saw the section on setting up a micro switch/piano wire for a
single frog. Is there a particular switch machine or circuit board I
could build to deal with the various "if" scenarios associated with
a 3-way turnout??
Thanks again!

Dave,
I'd like to answer your question, but I haven't seen one of these
turnouts yet. Even if I had, it would be hard to describe in
words.
I'll try to see one at my local hobby shop the next time I go and
I'll
make a drawing. Don't hold your breath waiting for the drawing.
I'm
working full time and going to school at night. My weekends are
taken
up studying. The drawing won't likely appear in my web page until
the
end of the semester.
In the interim, I suggest the following: Draw out the turnout.
Make
3 drawings; one each for the 3 routes the train can take. Label
the
stock rails + and - and follow it through the turnout. By noting
which set of points was moved to change the polarity of the rails,
you
will know which frog needs to be controlled by which set of points.
