You can visually check to see if the switches are making contact with the circuit board. The switches sit in a shallow recess in the top of the two pieces that holds the card reader.
Hold the pieces up so that your eyes are even with the top edge (you should not be able to see into the recess and should be able to see light through the card slot) and looking from the right side. They should be screwed together for this. Slowly insert a card into the slot from the normal side, the side you are looking from. You should see a total of four fingers lift above the surface of the plastic material. The first one that comes up is the one that tells the motor to start, it is towards the right side. Once the card hits the wheel, you will have to push harder to move it through without the motor but you won't hurt the card or the reader.
If you see less than four fingers pop up, adjust the finger that doesn't so that it comes up out of the well. Just make sure that it is also fully down in the well when no card is present. I had a card reader that wouldn't write to the cards and was able to diagnose it this way. I would also guess that the diameter of the replacement balls are to small.
Best of luck with it.
