If it ' s not too much bother , I ' d like to probe your mind a bit . What traits make whites close to men as groups , as opposed to blacks , and do you see any areas where blacks and men face similar discrimination that might arise from a threat narrative ? <| sep |> Classic let ' s try out your mettle fight . <| sep |> I ' ve never experienced this problem directly but am fairly experienced at troubleshooting the powercab . First course of action would be to stick a multimeter in the two little screw holes for the track wires on the little board with the red led on it . Is it putting out any voltage there ? If so then the track and feeder wires are the problem . Next would be making sure you are plugging the cab into the right plug on the board . I use the two on the front led side I believe , I don ' t have it in front of me right now . The single plug in the back is used for Daisy chaining and USB computer connections . After that I would try to do a reset of the power cab most likely . When you plug it in or turn it on it should flash on screen the software version . What is it ? Is it current ? To reset the cab , hold down the select loco key while plugging in the cab to the pcb bus board then release when it ' s plugged in . Let me know if this fixes it . If not I can troubleshoot further . Edit reread your post again . Make sure you are not in programming track mode . When you go to program your locos and everything you hit program and one of the options is program on main and another is use programming track . The programming track puts out less amps so if something is bad it doesn ' t fry the decoder , so if you are comfortable with your wiring from the track onwards program on the main for it to put out full amp power 2 amps I believe ? . Also how many different decoders have you tried ? You could have just messed with a setting on a decoder to prevent it from moving , so you could always reset decoders to factory resets as well . This normally fixes problems for me that I know are coming from the trains side not the powercab side , but you could do it just to eliminate possible error sources . What kind of decoder is it ? I ' ll tell you how to reset it or if you still have the paperwork it should say .
