Hi all, I've bought a second hand James. Its my sons birthday present and it isn't running. So the first thing I checked was the tender join. Gave it a clean, noticed that someone had opened the pins up so sorted that... No look Used contact cleaner on the wheels and brushes. Found some of brushs not behind the wheel so moved them back.. (but should they be in front? Goes a little bit What I don't understand in the main part of James the cabling shorts the two track lines.. And on the tender both + /- are on the pin... Surely this is not right?? But looking at the service guide it is Any advice
