Atlas GP15

Scale:
N Scale


This installation uses the following decoder:


This installation is for N Scale Atlas GP15 and uses TCS ASD4 Decoder and was performed by TCS.

While this installation is very similar to other ASD4 and AMD4 installations, Atlas has chosen to attach copper clips to there lighting contact pads which will be vital to a good installation. These copper clips are an excellent choice for Atlas because they prevent slight differences in board thicknesses from affecting the quality of the installation, and prevent the board from bouncing loose.

Once the frame is split by unscrewing the two frame screws and the lighting board is freed (as shown above) one must remove the lighting board clips and prepare to attach them to the ASD4.

Lastly install the decoder excactly as the lighting board had been, reattach the sides of the frame, and place the shell back on. When you install the decoder be sure that there is adequate space between the motor tabs to prevent them from shorting out on each other, the pads, or the frame.

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

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.
