Previously in my project I was using the motor shield V1 and everything was working properly until I had to replace this shield by the V2.
I took all the components off that were attached to the Arduino and left only the motor shield and the motor attached to terminals M3 and M4. I am running the example code of the library and the motor does not move. The motor is supplied by a 12 V external power supply. The Power LED of the motor shield board is on and I tested it without the VIN jumper, powering the Arduino trough my USB, and with the VIN jumper disconnecting the USB cable. It didn't work in any of the scenarios.
That's the motor (12V and 0.33A) that I am using: https://www.sparkfun.com/datasheets/Rob ... 011-25.pdf
And that's the code that I am running on the arduino:

This is a test sketch for the Adafruit assembled Motor Shield for Arduino v2
It won't work with v1.x motor shields! Only for the v2's with built in PWM
control
For use with the Adafruit Motor Shield v2
