With milling of the frame, they have been able to utilize a
AK-MB1 motherboard, WOW121 diesel decoder and UNIV-SH4C WOWSound kit installation for the double front and rear bulb version.
HO-Scale Life Like Proto 2000 GP38-2 shown prior to installation.
To start off this install, we must first remove the front and rear coupler screws highlighted above and their housings.
With the couplers removed, while gently pulling outwards at each end and along each side of the frame, 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 Life Like Proto 2000 GP38-2 shown with the shell off. Remove the wires from the original lighting board and remove it from the chassis.
Remove and discard the original 1.5 V bulbs as for in this installation, these will be replaced with a LEDs.
To allow a space for the motherboard and speaker, the frame must be milled as highlighted above to keep all the components below the original top of the frame.
Shown with the frame properly milled to accept the installation.
With the frame prepared, trim, tin or lengthen the wires as necessary.
Using double sided foam tape, attach the AK-MB1 to the frame and solder the motor and track pickup wires according to the included wiring diagram.
Using the same tape, with the 25mm X 14mm WOWSound speaker inserted into the UNI-SH4-C enclosure, mount this assembly to the frame as shown
and solder the wiring leads to the AK-MB1 according to the included wiring diagram.
In order to allow the sound to properly escape the shell for this installation, we decided to trim the rear roof top interior piece to expose the open fan.
Using a sharp blade and small screw driver, lift up and cut off the piece as shown above left. The open fans on this roof have loose fan blades,
so in order to prevent vibration which could compromise the sound quality, we recommend that you add a small drop of model glue to the
junction of the fan blades, spindle and in this case the other points highlighted to prevent movement and vibration.
As we replaced the original bulb lighting with LEDs, the front headlight and rear number board lights were left in their original locations, however the front headlight was soldered directly to the motherboard on the FWD and BLK pads as highlighted in red below. Using small lengths of TCS 3/32" shrink tubing, we insulated all of these solder leads. The front and rear top lights were mounted using a small dab of hot melt glue and shown in the two photos above. The front in between the lighting posts and the rear, tucked inside the lighting housing.
The installation shown complete. In testing it afterwards, there was some front light bleed between the two front LEDs, so we added a small
piece of black electrical tape to cover the top light as shown below.
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 Life Like Proto 2000 GP38-2 is now WOWSound equipped and ready to roll!
