The installation is for HO Scale Bachmann Spectrum 2-10-0 Russian Decapod . It uses TCS MC2P-SH digital decoder and was performed by Tom Gosser, Big Lake, Alaska

Important Soldering Tip:
Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use.
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157

You will need to unplug the two (2) wired connectors between the locomotive and tender, from the tender. Lift the tender from the drawbar. You will need to turn the tender over and remove the phillips head screw. Lift the top off from the front as it will rotate off of the two (2) tabs at the rear of the tender.


Once the tender shell is removed you will see a small pcb board mounted to the chassis. On top of this board is an 8 pin socket with a small jumper pcb plugged into it. Remove this jumper as this is where the Harness will plug in.


See that little yellow two legged capacitor in front of the 8 pin socket? You need to cut one of it's legs.


With that capacitor leg cut you can bend it over on it's side a little. You will notice that the MC2P-SH decoder extends past the end of the tender when plugged in. Notice that the MC2 decoder is face down.


Gently bend the Decoder Harness over so that the MC2 decoder now faces up and is oriented toward the front of the tender. In this position there is just enough room to reinstall the tender shell. Use some kapton or electrical tape to hold the decoder in place if you desire. Reinstall the tender shell in the opposite manner of removal.


Once the shell has been reinstalled connect the tender back to the locomotive.


The Russian runs nice and smooth with this decoder and installation is real easy!



Other solder tips: When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder the insulation will shrink back more. Try to not expose any more wire then 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.
