Help. Blew ECM fuse. Why???

[fireman68]

Last week I did the Caddmann mod on right side only (I also unplugged the green wires on the solenoids, taped them and put them in plastic wire wrap) and installed a TFI. I set the TFI at the recommended settings and then over the next few days rode about 150 miles with no problems. Today, I thought I would fine tune the TFI. I set the 1st pot to where the high idle would not increase anymore (2:45). I then started to try to adjust the 2nd pot. I started at 3:00. I then went for a short ride hitting the throttle pretty hard to see if it would hesitate. About the 3rd time, I blew the ECM fuse and the bike stalled. Any suggestions on what would cause this and where to start looking to fix it???
