Decided to upgrade PCB board on doodlebug so I can go DCC. Works great except no cabin lights. Any clues of what to look for? Decoder is Digitrax DN136PS. PCB is Bachmann 8142x-PCB03.
Looking at the pic of the PCB in the parts listing, there appear two solder pads off the 'L' and 'R' power runs. One is on the 'L' run, near the square opening on the long end of the board. The other is near the 'R' quick connect pad between the resistor cluster and LED light.
That are not marked on the top of the board, but it may be they are for powering the interior lights directly off power from the rails.

Was this issue ever solved? I have the same problem. How do you turn on the cabin lights after switching over to the new PCB board? I have installed a Digitrax SDXN147PS. All the L and R wires are soldered into place. Works will except no cabin lights.
Problem solved. The cabin lights are assigned to function one in DecoderPro. I just check off F1 Pad for forward and reverse headlights under the Function Map tab. When F0 is pressed the headlight turns on and so do the cabin lights. When you go in reverse, the headlight turns off but the cabin lights stay on. One more thing, the green wire must be soldered to the 8 pin connector in the appropriate location. I notice that some Digitrax decoder 8 pin connectors do not attach the green wire.
