HO-Scale Atlas C420 Ph1 high nose prior to installation.
To start off this install, we must first remove the front and rear coupler screws as indicated above in red and their housings.
With the couplers removed gently apply outwards on each end and along the shell and lift the shell off of the frame.
Take care with the handrails as you lift off the shell off so they don't break.
The locomotive with the shell removed. At this point, remove the wires from the original lighting board and release it from the frame.
Shown with the lighting board removed. Next, trim and tin or lengthen the wires as necessary for reconnection. Attach the AS-MB2-NC to the frame using
the mounting holes and solder the track and motor leads according to the included wiring guide.
Shown with the AS-MB2-NC installed.
Using double sided foam tape, secure the KA4 with Keep Alive™ to the front of the rear weight as shown and solder the connections to the motherboard.
Insert the 25mm x 14mm speaker into the UNIV-SH4-C enclosure and for this installation, to allow the speaker to fit onto the frame, we cut a small notch in the front bottom.
As the speaker enclosure will be visible inside the cab, we also painted it black to minimize it's appearance in the final installation.
Using the same double sided foam tape, mount the speaker assembly to the frame as shown, taking care to route the wires to avoid
potential pinches that could in the future lead to shorts.
