Ardumoto - one of the motors just wont go forward

Hello!

I got an ardumoto shield, and i am having some problems. maybe you can help me out:

when running the example code motor B wont light up the yellow light. it only runs backward, not forward. i tested the motor, it runs both ways. the other one runs perfect.

Any thoughts would be greatly appreciated.

Thanks!

I would double check the wiring and shield position against the guide https://learn.sparkfun.com/tutorials/ar … o-overview

The motor runs by itself, so it might be useful to swap their positions and the drive modes with each to isolate/eliminate variables

It also might help if you share a few photos of the wiring/setup
