The installation is for HO Scale Bachmann Spectrum Acela HHP-8 Loco. It uses TCS MC2P-SH-UK decoder and was performed by A.G.

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

The three upper pictures represent the locomotive prior to the decoder installation. The MC2P-SH-UK decoder will be fitted into the locomotive.


To open the body shell, remove the body shell by gently pulling the bottom sides out and lifting the shell. The upper picture shows the Bachmann original light board where 8PIN NMRA socket can be seen.


The close-up of the 8PIN NMRA socket. Remove the two metal plugs that locomotive came equipped with.


Insert the TCS MC2P-SH-UK decoder so that the orange wire is lined-up with pin #1 of the NMRA socket.


Here is a picture of the finished decoder installation.

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.
