    Hi,

    that should helps a lot:

    Here is a small pictuere tutorial how to isolate the ground:
    post7052.html#p7052

    Use a resistancemeter and measure if there is a connection between plus pole and casing of the motor.

    Anywhere there should be a video tutorial about isolating the ground..but i didn´t find it. Maybe youtube helps

    What kind of motor is that?

    best regards
    René
