Mincer - Help with a problem

[P-a-c_m-a-n]

Hi people,
Can you help me to identify the problem of this mincer?

-Wheel naturally with hand. Brushes and manifold visually are like new.
-I measured the voltage at the input of the switch and also measured the resistance of the switch in the on and off position and the resistance varies so I think that is fulfilling its function.
-However after the switch I can not quite figure out why I did not want to be parading the insulation. Leave 4-wire switch to the engine, red, white, blue and black. The red and the black will connect one to each brush, along the way insulated with sleeve I think have a few resistances and the white and blue connect directly to the coil.

So what actually are the symptoms?

Your post makes very little sense hence the lack of responses.
