Athearn ES44AC GEVO Decoder Installation featuring the GEN-MB1 Motherboard with Keep-Alive™, WOW121-Diesel Decoder, and 28mm Speaker 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

First, remove the coupler box screws and the coupler boxes from both ends of the locomotive.

With the couplers and under truck screws removed the shell should lift right off the chassis.

Remove the original lighting board from the chassis and remove the wires from the board tabs.



Next, we will prepare the speaker housing. Remove the screws holding the speaker in place.



Next, mount the 28mm Round WOWSpeaker facing into the speaker housing. This may seem counter-intuitive, but this permits the speaker wires to remain on the outside of the housing allowing for a solid seal all the way around.



Next, mount the GEN-MB1 on the motor just like the original lighting board and begin wiring it up according to the wiring diagram in your motherboard manual.

Solder in the lighting connections from the shell and install the WOW121-Decoder to complete the wiring of your installation.

Finally, you can replace the shell (it should slide over the installation easily), screw the shell in with the screws beneath the trucks, replace the fuel tank, and replace the couplers on the engine.

Your WOWSound equipped engine is now ready to run!


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.
