Dan,
Thanks.  
In researching this subject (_http://www.old-engine.com/maglma.htm_ 
(http://www.old-engine.com/maglma.htm) ),  I came to the same conclusion.  The 
battery/magneto ignition system only  works with a low tension system using an 
ignitor.  Since I have never seen  a battery/magneto system installed on an engine, I 
wanted to verify the hook  up.  This setup is probably used when starting 
larger engines where it  isn't possible to turn the crankshaft fast enough to get 
 the magneto to generate a spark.
However, there is another question.  In operating the low  tension magneto 
without being connected to the ignitor (open circuit) will it  cause any damage 
to the magneto?
