I'm building some keep alive circuits for my critters. The circuit will be housed in a separate tender with pickups on the wheels. So I have a couple of questions: 1. Where would be a good place to connect the keep alive to the decoders on a sound 0-4-0 Porter? B. What sort of pickups are available, or ones maybe you have built, for the tenders? Paul
it depends on the decoder you have ... most do not have keep alive wires on the outside ... chances are that you have to take off the shrink wrap, and solder directly to the decoder pcb.. if it matters, you don't need pickups, the keep alive draws power from the decoder pcb ..
Of course it does, silly me duh.......Thinking that electrical engineering collage might have been wasted, course it was nearly half a century ago
