The Atlas GP-7 shown with the shell on. To remove the shell, first loosen the railing on each side of the cab then gently squeeze the shell on
either side and lift it up.
Shown with the shell off. Clip the track leads and loosen the metal motor connection tabs to be able to remove the original lighting board.
Discard this board along with the attached light.
Shown with the original lighting board removed.
Using cutters, shorten the metal motor lead tabs and solder a new connection point to them.
With the solder connections in place, solder new leads to the motor, insulating the connections. Trim, lengthen and tin the wires to the track leads as necessary.
Attach the AK-MB1 and solder the track and motor leads to it.
To next install the lights, remove the light assemblies from each end of the shell. Trim the front and rear light tubes as shown above.
The front right behind the vertical partition, the rear right in front of the wing.
Next we installed new 3mm Sunny White LED's (Item 1288) to these trimmed tubes using a small amount of hot melt glue, adding
and insulating wire leads onto them. In this installation, we routed out the front light tube to allow the LED to mount flush into the tube.
You can also use surface mount LED's.
After the lighting is in place, insert the 25mm x 14mm speaker into the UNIV SH4-C
housing and using hot melt glue, attach this to the
top of the shell as shown.
With the lighting and speaker in place in the shell, solder these wire leads to the AK-MB1 according to your included wiring diagram.
You can plug in your WOW121 decoder.
Lastly, in order to keep the wires neat and prevent possible shorts, lace the wires into a bundle using lacing cord, which is a wax impregnated string
used for wire bundling and making harnesses. There are many choices of lacing cord available from Digikey www.digikey.com.
We use part number 802534B BK032-ND
Now you can close up the locomotive and reinstall the coupler assemblies. Be sure to be mindful of wire routing and reassembly of the shell as to not damage
or foul the installation. Your Atlas GP-7 is now WOWSound equipped and ready to roll!
