I have just checked a good TD160 motor that I have and can provide the following values.
Resistance of winding 1 measured between top terminal in your picture and 3rd terminal = 4.28 ohms
Resistance of winding 2 measured between bottom terminal and 2nd terminal = 4.56 ohms.
Colour coding of wires should be (from the top) red,black,black,blue.
There should be no continuity between any wire and the body of the motor.
Hope this helps.
