I just bought a NS 8-40CW Dash loco NIB and when I initially put it on the track, the right ditch light did not work. The left one did fine, but not the right. It is the Atlas Silver Series with the contact pads on the front of the frame with the copper tabs on the shell. I contacted Don at Atlas and he said to send it in, but is there a common problem/fix? There is no power to the pad, so it is not a contact problem. This is my 5th loco like that and it is wired like the both sets of ditch lighting coming from the board. There are seperate caps to each side and I suspect that the right cap is the problem...any ideas?
