Hi, you should have 2x leads / tails from the pcb which then solder to the motor. The 2 leads /tails are red and black, the red lead (+) will solder to the right hand side of the motor as it lays in the housing. I cant think why the leads are missing?? Being an old shaver there is probably not more information I can offer you, but contact if you want to try. Thanks Jason @ BRAUN SERVICE
