I was putting my Mega Tree up and while testing it I noticed 2 strnads were not working so I checked and 2 of my wires were loose (ground wires on the lights). I unplugged the power supply and re-installed the 2 loose wires and everything went haywire from there. I now have lights lighting up about 1/4 of the strand properly then half of the strand flickering and the last 1/4 not lighting at all. I have unplugged the sockets on the p12r and the lights unplugged are off but the others still will not work properly. I did not change anything from last year didn't even unplug everything from the controller and it was all working great last night except those 2 strings. Anyone have any ideas what I have done? The lights are about 2 meters away from the controller.
