Any advice appreciated.
I have a Hornby class 50 (Ark Royal) fitted with a Lenz 1035 decoder. I was bought the model as a present but it was some time before I could run it and when I did I found its running to be very erratic. It would stall when moving, or not start without a firm nudge etc and its speed was variable when running. I put it away as something to investigate when I had time. I then put it back on the track after a few months and it worked perfectly and continued to do so. I got it out again last week and it is back to its bad old ways. It seldom starts unassisted and when it is running it is worse on straight track than on corners. Sometimes when it stutters the head and tail lights briefly change ends, i.e. the headlight on the back will flash briefly. I have cleaned the wheels to no avail and wonder if I have a problem with the pickups. Does anyone have any advice on dismantling the thing or on how the pickups are attached or even any other suggestions.
Thanks
