TCS T1 Decoder Installation for HO-Scale Hornby 9F 2-10-0 Tank Locomotive . It was performed by Robert Lewis of 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

Pick-up is via the driving wheels of the locomotive, and the  outer wheels of the tender,  connection from the locomotive is via flexible contacts mounted  either side of the  locating pin.
To remove the tender body,  gently  pry the sides apart in the centre and it should slide upwards.

Either cut or de-solder the capacitor connected across the motor terminals, and bend the disconnected lead away from the motor terminal.
Disconnect the red and black wires from the motor terminals.  Join the 2 red wires together with the red decoder wire, insulating the joint on completion, and then join the black wires together with the black decoder wire, again insulating the joint on completion.
Connect the grey wire to the front motor terminal and the orange to the rear.



  Use double sided tape to stick the decoder to the  front ballast weight.  I cut the  unused wires right back to the  connector as the is little room to spare for excess  wires.  Replace  tender body.

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.
