This installation of TCS T1 Decoder is for HO Scale Model Power E8A and was performed by Jean Lacroix, Canada

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 model was custom painted to represent the E8 before it was painted in Via rail colors. Since all axles are powered and the unit is quite heavy, it is a good choice to haul long passenger trains. The first action you will have to do is to remove the front coupler of the locomotive by removing both screws on both side of the coupler box. The next step involves the removal of the body. In order to do this, you simply have to pull up the front of the body and then move it gently towards the back. The body should come off easily.


You will then have to disconnect all the wires that are hooked on the two motor poles through a small angled clip.


In the next picture, you can see that part. Keep those clips because they will be needed. Cut the bare metal wire and put it aside, it will be used shortly.


It is on those two parts that you will solder the grey and orange wires from the harness, one on each side of the motor. Then, solder the black wire of the harness to the black wires that come from both trucks. The red wire can be attached to the bare metal wire and then slide in the place it was before on the side of the motor, hold by the plastic clip that keeps the motor in its place, or soldered to a brass washer that is secured by a screw on the frame of the locomotive.

The blue and the white wires are connected to the front headlight Led as per instructions that come with the T1. The Led was slide in a tube in the nose of the locomotive. The yellow was not used for the backup light. Cut back the violet and the green and put liquid tape or electrical tape at their ends. Make sure you use shrink tubing over each connections between wires. The decoder is then simply installed just in front of the motor and held in place with double sided tape. You are now ready to reinstall the body doing the opposite of what you have done earlier.


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.
