[SEL] WOW-magneto charger

[Dave Rotigel]

Thanks Mark! Was not yanking your chain at all! Your "understanding  
and observations" have helped my understanding a good bit! One  
additional question with which you may be able to help: Can you make a  
guess as to whether or not my 100# magnet charger brings the charge up  
to (aproximately) what you call "the point originally intended by the  
magneto manufacturer?" (I'm taking for granted that the 450# beast  
would do that--and perhaps more!)
