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.
