    Heres how to work it out. Put one multimeter lead on to the output shaft of the motor & then check each conection with the other lead, meter set on ohms. The lowest reading will be the negative conection. (Ive asumed by his description its one of these motors)

    Black lead is conected to the motor drive shaft, as these motors are surounded by rubber insulation inside & the out side shell is quite often not conected to the motor shell.

    A few pics of whats in these motors & they are electronic speed control & adjustable. Normaly purchased in the voltage required & in CW or CCW. They can be reversed by dismantling & unsoldering the PCB from motor & shifting 180Deg & resolder & reassemble.
