Small problem I hope somebody can help with. Fitted a Digitrax DH165KO decoder into one of my locos. Crawls up and down, so not problem there, but no lights. See the photo which has two prongs at each end in the centre, and inside the power supply pick up which look like they should be the lights supply and return. Can't get an electrical connection between the power and the lights. Nothing either end, and with the F0 (lights) on, and tried it with it off as well. Contacted Digitrax who haven't replied so I thought I would try here. The decoder is fitted with a resistor so that the LED's should work, but I am not getting anything at all even when using a circuit tester. Incidentally the diagram supplied in the instructions is different from the decoder i have. Any help gratefully received.
