The installation is for the HO Scale Bachmann Baldwin RF-16 Sharknose . It uses the TCS M1 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 TCS M1 decoder installation.

 

Remove the four phillips screws that are circled in red.

 

Here is a picture of the original light board with the Bachmann decoder.

 

De-solder all wires from the board and remove the Bachmann decoder as shown in the picture above.

 

Remove the original Bachmann board.

 

Here is a close-up picture of the motor where you can see the capacitors (yellow) and resistors. All these parts need to be removed.

 

De-solder all capacitors and resistors so that the motor looks exactly as shown above.

 

Solder the gray wire of the decoder to the copper tab at the top of the motor. Use some Kapton or electrical tape to isolate the solder point.

 

Gently, solder the orange wire of the decoder to the copper pad on the bottom of the decoder. Be careful not to melt the motor casing.

 

.

Solder both red power pick-up wires together with the decoder red wire and isolate the connection point with the Kapton or Electrical tape.

 

Solder the blue decoder's wire to the brown LED's wire as shown in the picture above.

 

Insert 680 Ohm 1/4 Watt resistor between the decoder's white wire and the LED's gray wire. Isolate the connection with Kapton or Electrical Tape.

 

Here is a picture of the complete decoder installation. The decoder is placed behind the motor between the motor armature and 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.
