Do you know if the violtage on PIN 42 (Motor) and/or 41 (Logic) should be 5V all the time, when teh processor is running? I think the processor switches the voltage of the motor but maybe the drive-logic switches. My problem is, that I don't know what I should measure on pin 41 and 42 if the connections are proper. actually I don't get any voltage at all on those pins.
