 Hello Lionel!    Sounds like a bad connection or a open in one of your wires. Try another Motor that you know works & see what it will do. If it runs, your wires are fine. If not. then, there is a bad connection or a problem with the motor itself( although rare) The other thing you can do is connect the motor directly to the transformer using leads to see if it will run. Connect a lead to one of the Brushes & another to ground. Then use a wire from the top of the Brushplate where the Field is soldered to & run a wire from there to the second Brush connection & see if the motor runs. Hope this helps out & let us know what happens. Take Care.
