Aah nice one!:thumbsup: Glad you got it sorted.
I once had a DC40 where I soldered the wiring loom, got it back together and it was all good, except the stabiliser wouldn't lock unless pushed down by foot. Had to replace it with a completely new wiring loom and the stabiliser sorted itself out. When assembling a stripped one, everything's gotta be precisely right with these new Dysons around the ball area, as they're quite complex.
