This installation of TCS MC2P-SH Digital Decoder is for HO Scale Atlas Silver GP40-2 Phase I and was performed by A.G.

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

The three pictures above show the beautiful Atlas Silver GP40-2 Phase I with its shell on.


Remove the fan compartment as show in the picture above (just snap it off). Marked in red is a close-up of the original lighting board where the DCC plug can be seen.


Picture of the same board with the DCC plug removed. In the upper left corner of the DCC socket you can see a small triangular mark (circled in red) - that is the "pin # 1" indication (orange wire)


Plug the MC2P-SH into the DCC socket so that the orange wire is lined up with the "first pin indicator".


Place the whole decoder installation close to the original light board so that the fan compartment can be reattached.

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.
