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

HO-Scale Proto 2000 GP9 II shown prior to installation.

 

Shown with the shell off.

In order for space for the KA4 Keep Alive® in the front, the motor track pick up post must be trimmed as shown by the red bar above left.
To allow a space for the motherboard and speaker, the frame must be milled square above the original brush bracket as highlighted above to keep all the
components below to original top of the frame.

The front track pick up trimmed shown above.

With the frame milled, we tapped a screw hole for a #2-56 nylon screw to mount the AS-MB2 NC to the frame. You could also use double sided foam tape
to mount this to the frame, being sure to allow routing for the wires. With the AS-MB2 NC in place, using hot melt glue mount the KA4 to the front as shown.
With the 35mm X 16mm WOWSound speaker inserted into the UNIV-SH1-C, mount this assembly using the same tape to the frame and solder these leads to the
motherboard according to the included wiring diagram.

You can now plug in the WOW121 Diesel Decoder.

Lastly, in order to keep the wires neat and prevent possible shorts, lace the wires into a bundle using lacing cord, which is a wax impregnated string 
used for wire bundling and making harnesses. There are many choices of lacing cord available from Digikey www.digikey.com
We use part number 802534B BK032-ND

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 Life Like Proto 2000 GP9 II is now WOWSound equipped and 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.
