Hi. As I'm getting on in years and not good at all with electrics (Modern dcc) I am in the throws of downsizing my layout. I am now using a Hornby select, ( was using an Elite) I had a on off on switch that I used for programming locos on a separate track. But for the life of me I cant remember how I wired it up. I have searched the web, phoned Hornby, and asked Brian, but I need a diagram. ok 1st position powers the main track, middle position is all off, 3rd position powers the programming track. Please help with a diagram Thanks Pop (steampowered).
