 Can any one on the list tell me what the differences are(design and
 fabrication wise) between a 24V starter / 24 Alternator and their 12V
 counter parts.  I purchased an IO 550N with 24v components and I am planning
 a 12V system for my Legacy.  The components have 17 hrs on them so I would
 like to reuse if possible.  Since voltage control is provided by the voltage
 regulator which is separate for most aircraft alternates, in theory my new
 12V B&C regulator should be able to control the alternate output to 12V
 ????? I got the impression that things made not be all that different when I
 received my new standby alternate from B&C and it was label 12V/24V (dual
 purpose application) - I do not mind sending for new alt and starter but if
 not necessary would like to spend the money on x amount of other things.
