This installation is for a HO Scale Bachmann GP50 using a TCS WOW121 Diesel Decoder, AK-MB1 Version 2 Motherboard with built in Keep Alive®
and UNIV-SH1-C WOWSpeaker kit.
HO-Scale Bachmann GP50 shown prior to installation.
To start off this install, we must first remove the front and rear coupler screws and their housings.
With the couplers removed, while gently pulling outwards at each end and along each side of the frame at these four tabs highlighted in red above, lift the shell off of the frame.
Take care to release the handrails as you lift off the shell so they don't break.
The Bachmann GP50 shown with the shell off. Remove the wires from the original lighting board and remove it from the chassis.
Trim, tin or lengthen the wire leads to fit.
Using double sided foam tape, attach the AK-MB1 Version 2 to the rear of the frame as shown above and solder the motor and track pickup wires according to the included wiring diagram.
Using small lengths of TCS 3/32" and 3/64" shrink tubing, insulate these solder leads if neccessary.
In this installation, we replaced the original bulbs with LEDs, placing them in the original locations.
Solder these wire leads to the motherboard according to the included wiring diagram as shown above and secure them with a small dab of hot melt glue.
With the 35mm X 16mm WOWSound speaker inserted into the UNI-SH1-C enclosure and using double sided foam tape, mount this assembly to the frame as shown below.
In this installation, we created a channel for the front track pickup and front LED leads in the tape to ease installation.
You can now plug in your WOW121 decoder.
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 Bachmann GP50 is now WOWSound equipped and ready to roll!
