EasyDriver Stepper Motor Driver constant Vout to stepper?

I am having a problem with my EasyDriver Stepper Motor Driver. I am using a Arduino Mini Pro and this to step a small 12v stepper motor.

Running a 12v 2 amp power supply to the Driver.
The wiring is correct from the Arduino to the Board.

My problem is the Driver board is outputting a constant voltage on the 4 motor pins (pair A and pair B)

This even happens when the EasyDriver Stepper Motor Driver is just disconnected form everything and only is powered with the 12v power. The LED on the board is lighting up as well. (connected to the M= and GND correctly)

Is my board fried? I was under the impression it was not suppose to output constant voltage at any point. Any insight would be greatly appreciated.

thanks in advance

If you connect the Enable pin to ground does the voltage go away?

Are you sure it's not normal behavior, and the controller isn't just pumping power to the motor to hold it stationary?

If I ground the Reset pin the Vout drops to 0, but right back up when I reground it..

The motor will not respond to commands from the arduino (previously did a few weeks ago)

I don't feel like that is the case. The motor is also getting quite warm for not moving.

sorry, meant to add I did not try the enable pin. Just jump it to ground?

Yes, just tie the enable pin to ground. This should shut the motor off.

The motor will get warm / use electricity even if you're not spinning it -- the controller is locking the motor in place so whatever it's connected to can't move.
