  Have you done the calcs for your voltage divider?

  A one microamp load on a small 100 KV coil will drop the sec voltage to a
very small amount and make the measurement useless. The calcs are:
   
    R = V/I  = 100 000/10^-6 = 100 000 megohms !!!

  The resistance would have to be much GREATER than this to be of value.

   The only realistic method is to use the remote probe I showed in a post a
few days ago.
