This installation of the TCS T1-KA Decoder (with T-3.5"UK harness) with KA1 Keep-Alive Device is for HO Scale Atlas Track Cleaning Car and was performed by D.S.


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

First remove the second axle from the front truck as shown in the image below.

Next locate the screws highlighted in blue above and remove them from the car.

After removing the screws lift off the vacuum chamber lid (screen section), and the front roof panel.

Remove the 8-Pin dummy plug as seen on the left hand side of the image above.

Press down the black ring/blue button (next to the 8-Pin socket), plug the 8-Pin NMRA harness into the socket the dummy plug was in (make sure the orange wire pin from the harness is in the socket labeled "1"), wrap the excess wire around the button housing (be sure to avoid the screw holes), and kapton tape the decoder in place.

Next connect the KA1 to the T1 Keep-Alive attachment wires. If you chose the KA version of the T1 you will need to solder the blue wire and the black with white wire from the decoder to the corresponding colors on the KA1. If you chose the KAC version simply plug the decoder into the KA1. Now mound the KA1 on top of the T1 and Kapton tape in place.

Your track cleaning car should now look like the image below

Making sure that the blue button/black ring is unobstructed, replace the top pieces of the car, screw the front portion back in, and replace the wheels into the truck. You are now ready to run and clean your track!


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.
