HO-Scale Athearn Alco PA 1 shown prior to installation.
The Athearn Alco PA 1 shown with the shell off. Remove the original track pick up bars along with the front light assembly to prep the locomotive for the new motherboard.
Using a blunt tool, carefully push against the four plastic tabs found on the bottom of the tank frame to release the motor from the frame.
Lift the motor from the frame as shown above.
Remove the motor pickup clip from the bottom of the motor, flatten the two bent out tabs and solder a motor pick up to the 'top' of the clip. Be careful when removing this as there is a small spring located underneath that will be released when you do. With the new motor pickup soldered in place, insulate this connection with a piece of Kapton tape to prevent shorts.
Reinstall this clip and the motor into the frame, reversing the removal instructions.
Using a small amount of hot melt glue, mount the front LED to the front top of the shell as shown above.
With the 25mm X 14mm WOWSound speaker inserted into the UNI-SH4-C enclosure, mount this assembly to the frame as shown.
Attach the AS-MB2 NC to the shell with the same double sided foam tape and solder the motor and track pickup, LED, KA3 and speaker wires according to the included wiring diagram.
Using small lengths of TCS 3/32" and 3/64" shrink tubing, insulate these solder leads if needed.
You can now plug in your WOW121 decoder. Secure the shell wires with small pieces of Kapton tape.
Now you can close up the locomotive. Be sure to be mindful of wire routing and reassembly of the shell as to not damage
or foul the installation. Your Athearn Alco PA 1 is now WOWSound equipped and ready to roll!
