I have these too. The control monitors the return. My question is it through a relatively large resistance to limit current (like 3 ohms) or a small resistance (like 0.25 ohms) just to monitor the current. My guess is that it's a small resistance, but I'd like to make sure. That's why I asked for a resistance measurement.
