Evidently you would rather argue than explain yourself
Explain to me, that if you don't know how a circuit works, how this magic box makes things somehow easier? The goal here is to find and fix the problem. I'm all for that. If you cannot do that with say, a meter and or test light, then how is this device going to make that happen, or do so any easier? I KNOW how to find these problems. What I'm trying to find out FROM YOU is how spending this kind of money on something different will substantially change things. All you want to seem to do is claim "well hey it does"
