All sorted, thanks to all for input. Oh and don’t ask what I did, ‘cos I have no idea:-) I think the problem was me over complicating issues. I had the wiring and motors wired correctly, just the layout diagram on the ECoS wrong. I was coming into turnouts set against the flow, hence the shorts. I find it difficult to visualise the route though the double slip:-( Anyway, once again, thanks all for comments.
