I ran the test again using a 1.2 Ohm resistor as the load. The 1.8vac held

for the single and parallel measurements.

Secondary amps held at 1.83A for both the single and parallel measurements.

The primary amps were all over the place. I have given an average of 2.83

for single turn, and 2.98 for parallel, however these are suspect. There

are so many items plugged into the circuits, stabilizing the reading was a

......!

Still, it seems the only thing affected by the parallel secondary, is the

impedance of the primary, but to what end?
