Hi John,

I figured it out now; I know how you got the 5 volts! I was just 
overthinking things.
I figured out my acceptable reflected resistance, then my turns ratio , 
then my current and voltage - rather simple really. My only problem now is I 
dont have any sensitive( microamp range) meters around . The most sensitive 
one I have is a 0-1 ma .I can make it work ; I can also calibrate it to work 
with a 0-200 ua meter and just use the 0-200 ua scale on my multimeter for 
now.

 Thanks again
    Rick
