Has anyone any experience of dealing with a Hornby HM 4000 power controller?
I have a problem with one side of the controller. It controls two trains. The Yellow side has no response.
I have looked on-line for the circuit diagram with no luck. Tried a model railway forum, which wasn't helpful also.
The link below shows the front image of one. I can see from that somebody must have put a yellow sticker on mine to identify the left-hand controller.
It was purchased knowing it was faulty.
