HO-Scale Trainman NRE Genset II shown prior to installation.
To start off this install, we must first remove the front and rear coupler screws highlighted above in red 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 Trainman NRE Genset II shown with the shell off. Remove the wires from the original lighting board and remove it from the chassis.
With the original lighting board removed, trim, tin or lengthen the wires as necessary.
Remove the rear speaker housing screw highlighted above in red and the housing with it. Save these two pieces for later re-installation.
Insert the 35mm x 16mm WOWSound speaker into the original speaker enclosure and secure it with a small dab of hot melt glue. NOTE: You must be very careful to avoid getting glue on the speaker cone. Glue on the speaker will ultimately cause it to produce no sound and fail.
Temporarily set the AK-MB1 motherboard into place and using the wiring diagram as your guide, solder the track, motor, speaker and lights into place.

You can now plug in your WOW121 decoder.
To finish his install, in order for all the components to fit within the shell comfortably, carefully flip the motherboard over and mount it as shown in place. You can secure it with a couple of pieces of Kapton tape or with a few small dabs of hot melt glue. 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 Atlas Trainman NRE Genset II is now WOWSound equipped and ready to roll!
Important Soldering Tip
Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use.
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157
Other solder tips
When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire then half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
