Disassembling MM071

[gm171 kk]

I bought some spares recently consisting of various parts from MM112 and MM8113 so that I could convert my MM082 to NIR no.111. I used to the cabs from 112 and the rest of the body came from 113. To do this I had to strip 082 down to the chassis. No wiring was cut apart from the two connecting the chassis to each cab (light?). The loco has been reassembled with the new body. I haven't reconnected the wiring in the cabs yet in case they need to be taken off again. The loco has been placed on a live track with the default decoder fitted and it shows absolutely no sign of life. 

An observation I made is that 082 had four silver things at each end behind the four marker lights while the part for 8113 only had two. I know it is a different arrangement but am I right in saying there should be three of them for 8113? Also I can't see the likes of bulbs or wiring in the cabs for the headlights and markers lights, how are these connected to the chassis? These were fully functioning on my 082.

This is the first time I've taken a loco apart. Any help would be appreciated.

I'd splice the wiring back even temporarily in case you've cut a common return to the decode. I can't remember the 071 wiring diagram and although I have both these locos I' haven't looked inside in years so take this advice with a pinch of salt for now.

8113 has 4 newer LED markers. Iirc, the four prisms enable the light to be refracted to the outlet but I can remember where the LED diode is. They're usually covered in black plastic to limit light leak. The older 3-marker arrangement would refract from either a white or red diode but since they have separate outlet , it does seem like there should be a third prism for the red marker.... 

Looking in the DCC section forums may be of help
