This installation is for a HO-Scale Kato RS-2 using a TCS WOW101-Diesel Decoder, KA4 with Keep Alive™
and UNIV-SH4-C WOWSpeaker kit.
HO-Scale Kato RS-2 prior to installation.
To start off this install, we must first remove the front and rear couplers and their housings as highlighted above in red.
Once that is complete, the shell will lift off of the chassis. Do this by holding the fuel tank with one hand and lifting the shell off by
pressing up underneath the end platforms with your other hand
With the shell off, remove the two screws on top of the board as highlighted above in blue.
Next, remove the wires and the original lighting board while retaining the lights for reuse. Trim, tin or lengthen the wires as necessary.
Remove the front weight screw (highlighted in red in the small photo above) and remove the front weight.In this installation, we chose to trim this
weight to just beyond the screw hole (shown as a blue bar in the above photo) and reinstall it into the shell to retain as much weight as possible.
We also shortened the original lighting leads, added a 1/6w 1K ohm resistor soldered inline to the cathode, and then hot glued them in place onto the end of the
existing light tubes. Next, mount the KA4 in the shell, directly behind the LED, using hot glue or double sided foam tape to firmly affix it in place.
Now that the KA4 in place, insert the 25mm X 14mm speaker into the UNIV-SH4-C enclosure and using double sided foam tape, mount the speaker enclosure to
the top of the shell. With the KA4 and speaker assembly in place we can wire them both to the rear WOWSound harness.
Plug the KA4 into the WOW101 and using double sided foam tape, securely mount the WOW101 decoder to the top of the shell.
Solder the track, motor, and lighting wires to the WOW101 harness, insulating as necessary as well as mounting and wiring gluing the rear LED just like we did the front LED (including the 1/6W 1K ohm resistor on the cathode). See the included wiring diagram provided in the decoder literature for complete wiring instructions. We chose to add Kapton tape over the motor leads to hold the wires in place and to insure proper insulation.
Replace the shell and coupler boxes and your WOWSound equipped Kato RS-2 is ready to roll!
