The motor shield was purchased from Radio Shack as well as the uno. The motor is connected to the + and - connectors for motor A. Using a 9 volt battery to power motor. If I push on the two boards to try to get a better connection while it is sitting on the table it does nothing. It only works when I touch the bottom of the uno board around pin 3, I can post the code I'm using when I get home in an hour and a half.
