RE: Scooter motor [TANKS]

Steve,
Your proposal has some merrit to it.  Since I know almost nothing about electricity 
in general and electric motors in particular, learning this system may be easier.  
However, I think a translation manual is called for in cases where individuals are 
less inclined to move the more modern and relevant measuring system.  

Thanks,
Todd "electricity is a Black Art" Hutchins
