Thanks again Redgate, The Britannia (or tender?) is running fine on DCC. As you said "Tricky". However everything was fine. The main hiccup was deciding that the red wire from the loco. needed to be connected to the black wire from the decoder. However, having slept on that - no problems. Perhaps the most frustrating bit was putting the brushes back in with my clumsy fingers. But I have to admit things like that were easier 50 years ago. Regards, Jim.

Thanks Redgate, You have quite elegantly done what I thought might be the solution - isolating the brush holder from the end plate, leaving no need to isolate the end plate itself. If I had received no replies I would probably have attempted it off the cuff. Now after your tribulations I know where I am going. And it is going to save me hours of "suck it and see"! Your pictures show a unit exactly like mine, but mine DOES have traction tyres. One last question (I hope). IS this a Hornby loco? I bought it (used) as Hornby, but unusually I can find no markings except "SU" on the loco. chassis above the front bogie truck. By the way, I fitted a chip to a 3 rail Hornby Duchess I had already converted to 2 rail years ago, by ( simply in that case) isolating the rear, earthed, brush holder. Many Thanks Again, Jim.

Hi, I have been trying to fit a DCC chip to a (Hornby?) tender drive Britannia loco. Even with the 3 pole ringield motor brush plate fully isolated at the attachment screws I an getting an earth feedback to the earth brush holder via the armature spindle (shaft). I am at a loss how to overcome this with the few (small) tools I have. I will be very grateful for any advice. Hopefully I have attached photo's of the set up, which does not seem like any Hornby I have traced so far. Jim.
