VESC 4.12 Duty is always 110%. Possible short?

Hello FOCers :D 

I have built a couple of VESCs (4.12), but this latest one I built is exhibiting rather strange behavior.A

As soon as I connect the vesc via vesctool, the dutycycle green bar in the lower part of the screen shows 110% duty cycle, and it always stays there (ocassionally it jumps around, but most of the time it is solid 110-20%). 

I am guessing it is either a hardware failure (MOSFET? Shunts? DRV?) or a short somewhere. 



Does anyone have a solution to this problem? Thanks so much!
