5) Refit the shell, test the model then refit the couplers



2012 run: with 8 pin plug


1) Remove the couplers then splay body around underside from chassis and lift off.

2) Just to the left of the decoder pictured below is where a plug and socket resided "WSW". This can be removed if necessary in order to provide more room for the decoder. The wires are soldered directly to where the plug mounted to the DC board. Black on the left, red on the right, as pictured.

3) At each end of the motherboard, there are 4 plugs on the underside. These interfere with where the speakers will be positioned and therefore need to be removed. Relocate the red and black wires to the top side of the PCB, cutting the plugs off as you go.

4) Fit the speakers in place and wire to the decoder. Ensure speakers are wired in parallel and in-phase.

5) Apply Kapton tape or equivalent to the underside of the PCB on top of the speakers so as to prevent any chance of a short circuit.

6) Once done, test the model then refit the body and couplers
