Kato GE P42 "Genesis" (All phases)

Scale:
N Scale


This installation uses the following decoder:


This is the installation of the 8 function TCS K0D8-A digital decoder for N Scale Kato GE P42 (all phases) performed by TCS

The TCS 1/4" Kapton tape used in this installation is not supplied with the decoder and needs to be purchased separately at your local TCS dealer or directly from us.





The three pictures above show the beautiful P42 Genesis Phase II engine prior to the K0D8-A decoder installation.

Use a small piece of Kapton tape around the track power pick-up rail (marked in red) so that it is isolated from the motor tab. This is a very important step of the installation and ignoring it might damage the decoder!!!!!

The picture above shows properly done isolation of both motor tabs.

We suggest using small amount of solder to connect the motor tabs with the decoder (see picture above). Tint the copper pads with a little amount of solder and than solder motor tabs to the decoder.That will provide solid electrical contact.

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

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.
