Disassembly

All work is contained within the tender. There is no work required of the engine.


The tender is disassembled through four screws holding the frame to the jacket.


DCC fitout

The following items were then fitted to the tender:


ESU (58820) LokSound V5 Micro DCC 8 pin decoder with N class sound,

DCCSound Stay-alive unit,

DCCSound Premium sugarcube speaker (8 ohm)


2013 non-DCC ready version:

This model comes without a DCC socket, so a decoder must be hardwired. Wiring is as follows:


Decoder:

White wire: Front headlight

Yellow wire: Rear headlight

Green wire: Aux 1 red tender marker lights

Grey wire: Orange motor wire (!)

Orange wire: Grey motor wire (!)

Black wire (usually left side track): Tender and engine red wires (!)

Red wire (usually right side track): Tender and engine black wires (!)


Note: If consistent colour coding is required, CV29 would need to be set to reverse direction of travel.


In the following example, an NCE non-sound decoder was fitted.





2017 DCC ready version:

The 8 pin plug is removed (DC operation), and the decoder plugged in. The speaker is then fitted in the tender using double sided tape. All electrical contacts are protected from possible short circuit with the metal model. The decoder and stay-alive are then located in the tender jacket.

Finally, the tender was reassembled and tested with the engine.
