Good morning all,
In a collection of 2nd hand track, I acquired what would appear to be a LGB 10340 shuttle unit all fitted into a buffer stop as you would expect.
However even after fighting my way through the minefield of incorrect wiring diagrams and their subsequent revisions, I still can't get the thing to do what it should. It starts the loco slowly and builds up speed as it should but does not stop at the cut / diode just continues to increase speed. The direction of the controller makes no difference, it still only goes in the same direction. I've tried increasingly larger diodes (Starting with IN4004's) to no avail, nothing seems to bring it to a halt and reverse as it should. I am using an analog system. Oddly every image of the 10340 shuttle unit I can find shows two blue dials, but mine are red. Otherwise it appears identical, and shows no sign of any overheating or damage. Can anyone confirm if the two cuts / diodes are supposed to be on the same side of the track as shown in the wiring diagram or on opposite sides. I want it to operate in mode 1. Does anyone know which position the 2 little switches need to be in?
Have I got a defective 10340 or is this something else entirely? (Made for digital control perhaps?)
Any advice or insight would be most helpful as it's driving me round the bend.
Thanks for looking.
Paul.
NB; Shouting at the damned thing and threatening to throw it in the pond has no effect either. (Trust me, I've tried.)
