TCS M1P-UK Decoder installation for N-Scale Con-Cor Aerotrain.
There is not much to this installation it is pretty basic. What you need to do is find the second car; the one that goes behind the locomotive.
The shell must be pulled off and you will find a small 8 pin NMRA dummy plug located under the board. This plug just makes simple connections for the train to operate in DC only but by removing it and plugging in one of our decoders it will run on DCC.
You must start first by removing the two wires clamped down on each corner of the factory board by the copper tabs. Once they are removed the board will lift off the pin as you see in the picture below. Once the board is popped up it will be able to swing side to side, this will give you access to the plug on the bottom of the board to be taken out.
Once taken out notice there are numbers for each pin that will be your guide as to which way you will need to plug our decoder into the NMRA socket. You want to make sure that the pin with orange wire attached to it is plugged into the same spot pin 1 was connected to in order that you may avoid damaging the decoder.
After the decoder is plugged in all that is left to do is tape the decoder down and run the wires out of the way like in the picture below.
The final step is to put the shell back on the car and hook up the cars together to run the train.
Important Soldering Tip
Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.
TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.
You can order this solder from the following retailers:
Digikey - PN:KE1110-ND
Techni-Tool - PN:488SO6775
Other solder tips
When stripping wire, only strip a tiny little bit of the insulation. Strip no more than a 1/32 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire than half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
