I've received mine and my Ultrascale conversion wheelsets to make a P4 version. Once I had run it in for half an hour in each direction, I dismantled it (with a certain amount of difficulty over the recalcitrant brakegear which was very firmly glued in place) and took off everything I needed so I could get to the screws which hold the redundant tension lock couplings to remove them. All done until, as I came to put it all back together again, I noticed a brown wire that was no longer connected to the PCB. It is not obvious (to me at least) where I might re-connect his loose wire - it is the one that is attached to the brush holder to the right of the flywheel. If anyone can advise me where I should solder this wire, I would be extremely grateful.
Many thanks,
Stan
