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

Just remove the cab. Dismantling the locomotive any further is difficult and unnecessary.

Disconnect the black wires and the capacitor from the motor terminals.


Connect the decoder, making sure to insulate joints from pick up wires


Re assemble cab, decoder is stuck with double sided tape to rear wall of cab, wires can be painted with matt black paint to hide them.

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.
