HO-Scale Kato RS-2
shown prior to installation.
To start off this install, we must first remove shell. Do this by gently squeezing the shell on both sides and carefully lifting it upwards.
Shown with the shell off and the original lighting board already removed. To remove the board, separate the metal motor tabs and simply lift it off of the chassis.
Trim each motor lead tab and solder a connection point to each as highlighted above in red. Remove the walkway to reveal the track pick up.
Solder a wire lead to each motor pickup and insulate with shrink tubing. At this time, solder a low profile connection point to each side of the track pick up
and branch these leads to be able to connect to each end of the AS-MB2-NC.
Attach the AS-MB2-NC to the frame and solder the motor and track pickup wires according to your included wiring diagram. Replace the walkway.
Next, remove the front weight screw above highlighted in red and with it the front light tube and weight from the shell. This weight will be discarded.
Using a small mitre saw, trim the light tube just beyond the front lens element as shown above and place it back into place into the shell.
With the light tube in place, insert the 35mm x 16mm speaker into the UNIV-SH1-C enclosure and using hot melt glue, mount this assembly into the top
front of the shell right behind the light tube as shown above. NOTE: You must be very careful to avoid getting glue on the speaker cone. Glue on the
speaker will ultimately cause it to produce no sound and fail.
With the lighting in place, using hot melt glue, mount the KA4 Keep Alive™ to the shell directly behind the speaker and solder these leads to the AK-MB2-NC.
You can now plug in your WOW121 decoder.
Now you can close up the locomotive. Be sure to be mindful of wire routing and reassembly of the shell as to not damage
or foul the installation. Your Kato RS-2 is now WOWSound equipped and ready to roll!
