The installation is for HO-Scale Fleischmann 4375 BR103 . It uses T1 decoder and was performed by Ric Bogart of Osborne Park  W A,  Australia 

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

 This particular model as it has lots of room for the decoder and cable.Firstly disassemble the loco (as per the operating instructions for the service of the unit) Lift the locomotive casing and remove.


The pantographs have to be isolated from any circuits there is a switch that selects between pantograph and track pickup a small strip of insulating tape will do the job, the switch is then replaced with a link wire Lights must then be isolated on one side (running the existing lamps on half wave power)

Following the decoders instructions the      red wire -----to the right side rail pickup   orange wire -----to the motor replacing the  original brown wire   black wire ---- to the left side rail pickup    grey wire ------to the motor replacing the black wire      ------ white to the forward headlight     ----- yellow to the rear headlight

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.
