Why do you want to do this? The motor should have the current rating stamped on the nameplate.
If you mean measuring the reference voltage or vref, the positive probe should be touched to the round metal circle to the right of the heat sink on the middle-right of your picture. The circle is the trimpot, which you turn to adjust the vref.
