The blue wire is crimped on with a brown wire and comes from the switch. Theres 2 black and 1 red from the cord reel, one black goes to the motor and one goes to the pcb, and connects to the same ring on the cord reel so I assume its neutral, one red goes to the pcb then a red out to the switch on the other side and the red that clips onto the motor. I presume the pcb steps the live voltage up and down as needed by ots command then?
At the hospital now for the last appointment before the baby is here, will plug it in tomorrow.
Got 5 hoses, 4 filters and a load of my polishing pads in the washing machine at home too, hopefully that will finish clattering around by the time we get back!
