  If you really wanted to know the voltage and were willing to spend
  some time to find it, how about taking a series of measurements,
  using a voltage divider with a different impedance for each
  measurement?  By plotting measured voltage against voltage divider
  impedance magnitude and extrapolating to infinite impedance, it
  seems that a reasonably accurate value for the secondary voltage
  can be measured.
