This installation is for a HO-Scale BachmannJ Class Steam using a TCS WOW121 Steam Decoder. This install was performed by TCS.
HO-Scale BachmannJ Class Steam prior to WOW101-Steam Decoder and UNIV-SH2-C installation.
To begin this installation, we must remove the tender shell. After lifting the small top knob at the top of the separate
box on the tender, locate and remove the two screws underneath the frame on left and right sides of the locomotive as indicated in red above.
Next remove the third screw located at the center rear of the locomotive, as highlighted above, and the coal tender is now free to lift off.
Carefully remove the 3 screws, as indicated above in red, from the original lighting board and remove the lighting board from the frame.
With this board removed, identify, organize, trim and tin the wires as neccessary.
Using hot glue, mount the hard wired 28mm speaker inside of the UNIV-SH2-C housing and then mount this face down onto the frame over the speaker holes. To fit this assembly, we found it neccessary to cut a small verticle notch into the housing to accomodate the coal tender screw receiver upon reinstallation.
To visually minimize the speaker assembly when completed, we painted the housing with black paint on the exposed side.
At this point, solder the track and motor wires to the corresponding wire on the 9-pin JST connector.
Follow the wiring diagram that came with your WOW101 decoder to insure proper wiring.
Plug in the WOW101 Steam decoder and using foam, double sided tape, install this and the KA3 into the top of the speaker aeembly.
Wire the front light according to the wiring diagram included with your decoder.
This locomotive uses an LED for the headlight so we will need to add a 1/6w 1K ohm resistor onto the cathode side of the lighting leads as shown above.
As the space is minimal within the coal tender box, gently roll and lay the wires on top and secure with Kapton tape.
Reset the tender shell onto the frame, reinserting the bottom screws and place the box back on top and your Bachmann J Class Steam WOWsound equipped locomotive is ready to roll!
