OK thanks. 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.
