I had to read your comments several times and almost felt like I was back in Chemistry class. You are thorough in your description and I believe I understand what you are saying. Since my Univolt is long gone and the current Magnatek does not have the capability to work the indicator, I will just plug in my electrical tester which will let me know that AC current is moving through the circuity breaker box to the wall plugs. If I plug in, I will know it anyway but it would have been nice to have it working.
