3.3V/11A is 0.3 ohms, so if that’s accurate, the leads are also about 0.15 ohms, which seems a bit high.

However, if you leave the bench supply connected you can trace tens millivolts instead of single-digit milliohms. Also, more importantly, you have a built-in Kelvin connection so you don’t care about the contact resistance. That makes it a much better method than using an ohmmeter.

Good hunting!
