I posted this to the Digitrax IO Groups also, sorry for the duplication, but I want to ge this in fron of as many eyes as possible. "Here¡¯s a strange problem we have at the Amarillo Railroad Museum. We have a portion of the layout powered by a DB200+, and the off line led is glowing, We have totally disconnected it from the layout, including no LocoNet connection, it is only receiving input power from a Digitrax PS2012 set to HO scale, We have switched out the DB300+ with two identical DB 200+ boosters and the off line led glows regardless of the DB200+ used, It makes no difference if the PS2012 slide switch is set to N, HO or O/G scale. We see a steady 18-volt input from the power supply, we get zero on the output side, regardless of the booster we use. It seems that the problem must be from the input, but why? What is going on?"
