Many thanks to Joe who suggested that we look at measuring current at the input return of the CW. We did a couple of LTSpice runs and you have convinced us! And, in the process, a student learned to build stuff in LTSpice, something that will come in handy next year. We are still figuring out how to measure the negative voltage with the Arduino, leaning towards using an opamp.
