After my experiment connecting an old 6 pin decoder to an 8 pin plug I thought it best to get a supply of decoder wire.
Once on the bench it was obvious that I would be forever losing and then untangling it so I had to come up with a way of overcoming the problem. On my last stay in a hotel, I made a point of saving all those free pots of shampoo they put in the rooms, so I drilled a hole in the lid to feed the wire through and put the rest of the wire in the pot. I also added a neodymium magnet to each pot to hold it down n place on the workbench.

I started off by unsoldering the pins from a decoder to solder wires directly to the solder pads but even though I checked for no stray wires or solder the thing still went up in a puff of smoke. Retraced my steps with another old decoder (I have plenty

) and got exactly the same result.
Checked everything again, confirmed the wiring colours matched the pin numbers, but on the third attempt I soldered the wires directly to the ends of the pins.
This time no smoke and a perfectly working mini decoder for tight installations, but I damned if I know where I went wrong on the first two.
