Tilehust, Reading, United Kingdom
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 http://www.techni-tool.com
Remove the slotted screw from under the cab, and then lift the body from the cab end, tilting it upwards will release it from the front chassis mounting point.
The decoder socket is at the front. Remove the blanking plug and fit the decoder plug, the orange wire going to Pin 1 marked on the PCB.
There is just enough room above the socket or in the smokebox to house the decoder.
Refitting the body is the reverse of the removal process.
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.
