Didnt you say that MS was one that I built? That is def not one i built or someone has rebuilt/changed portions of the MS. Portions of that board are not my work and some of it is not my materials. That board has been altered.

If it does it on the stimulator then something on the board is not right. See the jumpers on the bottom of the board? Make sure they are not shorting out to something

Edit: try loading an older Firmware into it and make sure its not a firmware glitch
