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

This installation is for a HO-Scale Athearn Genesis FP45 using a TCS WOW121-Diesel Decoder. This install was performed by TCS.

HO-Scale Athearn FP45 prior to WOW121-Diesel Decoder installation.

To begin this installation, remove the two screws underneath the frame on each end as indicated in red above and remove the coupler box.

Next remove a second set of screws located on either side of the locomotive as highlighted. Gently grasp the shell on either side and lift off.

The locomotive shown with the original lighting board after the shell is removed.

Carefully unclip and with this board removed, identify, organize, trim and tin the wires as neccessary.

Install the new GEN-MB1 motherboard onto the existing clips and solder the track and motor connections in place.

Next, solder the speaker wire and lighting connections to the motherboard as per the included wiring diagram and carefully attach the WOW121 decoder.

Solder the wire leads to the 25 x 14mm speaker, press it into the INT-SH1 enclosure and hot glue this assembly into place.
It might be neccessary to slightly sand a small portion of the sides on the speaker enclosure to properly fit between the uptrights and ensure a good fit.

To ensure a neat appearance and prevent pinched wires and potential shorts, we lace the wires into a harness.
You are now ready to reinstall the shell, the bottom screws and couples to finish the installation. Your WOWsound equipped locomotive is 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.
