Well a nice cup of tea always frees the mind to see the obvious, time to review the service sheet to identify where the wire should go. Clearly the diagram makes no sense, there is only one wire and I have two...

Good job Peter's spare are on the ball as I now have new brushes and new clip (along with some other bits a bobs I could resist), had to pay for the postage anyway so in my mad world of economic it all made sense.

ah ha, I have it! good gads Carothers, my two wire are actually only one split by the suppresser, So the wire goes to the pick on the that connects to the wheels. Time to get the screwdriver out and strip the model down a little bit more. And behold there it is a tiny copper tab, job done I hear you say, well I would if... no I've already done that one. But No! hold fast and slow down I've never soldered in my life!

What should I do, maybe put the old Gronk back in the box and pretend I never found her or maybe, just maybe I should order a soldering iron and strike whilst its hot. I need something that will help me make up my mined. Time to consult the tea leaves...
