4 short sections of black heatshrink tubing are cut off and slipped over each of the engine's wires ready to be moved into position to cover the soldering joins between motor wires and DCC decoder wires.
I decided to sever the connections to the front light incase that caused a short circuit to the chip - not sure about that but better safe than sorry.
Changed my mind and placed the heatshrink tubing around the 4 wires coming from the chip - they were longer and easier to place the tubes around. I'm only using 4 of the plethora of wires coming from the chip. The others are to send instructions to headlights, tail lights and other functions.
Next one slides the heatshrink tubing over the solder joins and melts them into permanent position with a hairdrier. This prevents the metal joins touching any other metal and short-circuiting.
Finally, one joins the actual chip (the black square in picture) to the wires by plugging in that white endpiece that the wires go into. A most UNSATISFACTORY fit - does not feel plugged in at all but one is scared to push too hard in case something breaks.
Oh well, we'll see what happens tomorrow when a short section of track is wired up to the DCC control system. Do not believe it will work, I'm afraid.
