TCS DP2X decoder installation in a GWR Diesel Railcar - performed by Robert Lewis.

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

Remove the 4 buffers marked with the blue arrows, they just pull out.  Remove the 2 screws, red arrows, from the underside. The body should then lift up off the chassis.

The decoder blanking plug, the arrows shows the position of pin 1.  Lift the plug upwards to remove.

Fit the TCS DP2X, as shown, noting the orientation.  Test installation on your test track before refitting the body, which is the reverse of the removal procedure.

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.
