This installation of TCS MC2P-MH "Flipped" or A4X Decoder is for HO Scale Kato EMD GP35 Phase 1C with Dynamic Brakes 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

Grasping the shell at the center top of both sides (being careful not to crush the grills), lift the shell straight up and off of the chassis. Plug the MC2P-MH into the socket so that the orange wire of the decoder goes into pin#1 of the socket.

Some Scotch tape was used to fix the decoder to the chassis so that it does not get into locomotive's drive circuit.

As an alternative, we recommend using our TCS A4X , 4-function drop-in decoder that will fit this engine perfectly and will give you option of extra light functions! (See Below)

Hold the shell in one hand and the chassis in your other hand. Lining up the front of both pieces, lower the shell onto the chassis, keeping the lower edge of the shell parallel with the chassis.

 


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.
