This installation of 1B-MB1 and WOW 121 Diesel Decoder is for HO Scale Atheran Genesis SD75M and 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

Atheran Genesis SD75M prior to installation.

Begin this installation, remove the screws found on each coupler and the coupler boxes.
Grasp the sides and each end of the shell to gently pull outwards and release it from the frame.

Atheran Genesis SD75M with the shell removed. On this locomotive, the cab is a separate part and must also be removed. Very carefully grasp the sides of the cab andgently squeeze inward and lift it up. At this point, unsolder the wires, taking note of their function, then uncip and remove the original lighting board from the frame.

Clip the new GEN-MB1 onto the frame and solder the track and motor leads in place.

With the 35 x 16mm speaker wired and inserted into the UNIV-SH1 enclosure, using hot glue, mount this assembly to the frame as shown.
In this installation, we used Kapton tape to secure the track lead wires to minimize movement and prevent shorts.

Following the included wire diagram, solder the lighting leads from the shell as well as cab onto the motherboard.
Attach the WOW121 Diesel decoder to the RTR-MB1 motherboard.

In order to keep the installation neat, prevent loose wires and shorts that might result, lace the wires into a bundle for reinstallation of the shell.
Reattach the cab and shell in reverse order. Install the coupler boxes and screws and your WOWSound equipped Atheran Genesis SD75M locomotive in 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.
