To check for voltages coming from a specific part (i.e. sensor wire, power supply, DC 
motor), place the negative lead of the multimeter in pin P9 (ground) and the positive 
lead in the desired pin.  Follow the pin voltages listed above to diagnosis a specific 
part.  The power supply must be plugged into the power jack, and the console should 
be plugged into the console cable to receive accurate readings.
