The installation is for HO-Scale Fleischmann 4228 BR 211. It uses EUN651 Drop-In or T1 (some modifications required) decoder and was performed by Ric Bogart of Osborne Park WA, Australia.
First, remove the screw from the bottom of the loco (as per the operating instructions for the service of the unit) Lift the locomotive casing and remove. This loco has been built for digital conversion but you need a NEM 651 socket decoder (hard to come by and a little expensive) I chose to hard wire a T1 decoder. Once the 651 plug is removed the motor is isolated from the track pickups and the lights are isolated from one side to allow half wave powering. Following the decoders instructions the red wire -----to the right side rail pickup (Fleischmann's blue) orange wire -----to the motor black wire ---- to the left side rail pickup grey wire ------to the motor white to the forward headlight ----- yellow to the rear headlight. Reassemble and you are ready to roll.
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
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.
