HO-Scale Atlas DASH 8-40B prior to installation.
To start off this install, we must first remove the front and rear coupler screws as indicated above and their housings.
Once that is complete, grasp either end and along the shell and gently pull out to lift it off of the chassis.
With the shell off, we can now remove the original light board. Remove the wires from the board and the board can easily be removed.
Shown with the factory light board removed. We can now attach the AS-MB2 to the chassis.
Shown with the AS-MB2 mounted and the JST connectors installed.
Next, using double sided foam tape, mount the KA4 Keep Alive™ on to the rear of the front weight as shown and solder the wires to the AS-MB2 motherboard
according to the included wiring diagram. Remove the rear weight plug at this time to facilitate mounting of the speaker assembly.
Mount the 28mm speaker into the frame port as shown and solder the speaker wires onto the motherboard speaker pads.
Using a file, cut a small notch in the weight on the opposite side of the speaker as shown above in red, to allow the speaker wires to easily pass through and re-insert this weight into the frame. It is important to do this in order to retain as much rear weight as possible and enhance the sound output,
You can now plug in you WOW121 decoder.
