This installation of TCS T1 Decoder is for HO Scale Lima Class 09 and was performed by Robert Lewis of Tilehust, Reading, United Kingdom.
Lima Class 09 Diesel Shunter (Switcher)
To remove the body undo the slotted screw at the front of the locomotive. The rear of the body is held in place by 2 lugs from the chassis which pass through the rear buffer beam. Carefully lift the body off, gently sliding backwards to clear the lugs.
De-solder the capacitor wire (1) and the left pick-up wire (3) from the rear motor terminal, then de-solder the right hand pick up wire (2) from the front motor terminal. I have sleeved the disconnected capacitor wire just in case I want to return to normal DC operation in the future.
Join the red decoder wire to the right hand pick up wire, insulate the joint. Join the black decoder wire to the left hand pick up wire and insulate the joint. Solder the orange decoder to the rear motor terminal and the grey to the front terminal.
I have left all the wires long just to allow for any future modifications as there is room within the body. I sleeved the unused wires and used short pieces of insulation sleeving to bundle them together. I also used the same method to tidy up the used wires.
Test the installation
I used hot melt glue to hold the wires to the top of the ballast weight and to hold the decoder in position. Re-assemble the body to the chassis, taking care not to over tighten the screw.
Important Soldering Tip
Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.
TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.
You can order this solder from the following retailers:
Digikey - PN:KE1110-ND
Techni-Tool - PN:488SO6775
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.
