HO-Scale Atlas RS-1 prior to WOW121-Diesel Decoder, AK-MB1, and UNIV-SH4-C installation.
To start off this install, we must first remove the front and rear couplers and their housings.
With the couplers removed apply a gentle squeeze to the shell and lift the shell off of the frame.
Take care to release the handrails as you lift off the shell so they don't break.
With the shell off, we can now remove the factory light board. First remove any wire clips and disconnect the wires from the board.
Once the wires are loose, the factory light board can easily be unclipped from the motor mount.
Now with the factory light board removed, we can now clip in the AK-MB1.
With the AK-MB1 inplace, next, solder the motor and track pickup wires according to the wiring diagram in your motherboard manual.
In this installation, the forward light tube needs to be trimmed to allow space to install the speaker housing.
Using the light tube mitre box, this becomes an easy task. Simply insert the tube as shown in the box.
Using the provided saw, Carefully cut through the tube.
The result is a perfectly cut to length light tube, ready to install.
With the cut light tube placed back into the shell, using a dab of hot glue, mount the speaker assembly right behind the front tube in the top of the shell.
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.
Next, using another dab of hot glue, glue the LED directly to the top of the light tube. The light will easily translate into the tube and
through to the front light lens. Solder these lighting leads to the motherboard as shown on the wiring diagram in your motherboard manual. The AK-MB1
is configured for LED use and has built in current limit resistors in series with the light outputs for LED use so we added no additional resistors.
Lastly, plug in your WOW121-Diesel decoder.
In order to keep the installation neat and tidy and prevent loose wires that might result in a short, lace the wires together into a bundle using lacing cord.
You can now reassemble the shell in reverse order. Be sure to be mindful of wire routing and reassembly of the shell as to not damage or foul the installation.
