This installation of AK-MB1 and WOW101 digital decoder is for HO-Scale Atlas GP38-2. This installation was performed by TCS


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

The Atlas GP38-2 prior to installation.

 

To begin this instalation, first unscrew the coupler screws at each end of the locomotive and remove the coupler box.

With the coupler boxes removed, gently grasp the shell on the sides and while pulling outward on each end, carefully lift the shell from the chassis.


Remove the wires from the original lighting board and unclip this board from the frame. At this point, trim and tin the wires as neccessary.

After attaching on the AK-MB1 motherboard to the frame, solder in the motor, track and lighting connections according to the diagram on the literature that came with your motherboard. NOTE: the AK-MB1 has built-in current limiting resistors for LED's so you do not need any external resistors.

After wiring in the 35mm x 16mm speaker into the UNIV-SH1-C enclosure, using foam double sided tape, mount this assembly in to the top of the shell
and solder the leads to the motherboard.

To complete this installation, plug the WOW101 decoder onto the motherboard. To ensure a neat and clean appearance and to prevent pinched wires and potential shorts when reassmbling the locomotive, we lace the wires in bundle. Reattach the shell and the couple boxes and you have succesfully installed WOW sound into your locomotive and are ready to roll.

 



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.
