BLtouch+ Rampsboard Smoking

Hi all,

I was hoping someone could help me out with this issue.
I just installed BLtouch onto my ramps 1.4 and I got it working. I tried to heat up my bed and extruder and My LCD kept on shutting off. I thought it was weird and I tried again, then I smelled burning plastic.

I looked at my board and the fuse was smoking and I burned my finger on the mosfet. Has anyone run into this issue? I have attached a picture of the board. It was working perfectly fine before installing BLtouch. I do not think I shorted anything out.
