This installation documentation is for the Walthers Mainline-series GE ES44 GEVo. This installation uses the WDK-WAL-2 WOWKit and was performed by TCS' very own Dan M.
Note: This installation features a locomotive with ditch lights. The factory setup for these lights are MATCHED PAIRS of wires going to the front and back for F1 through F4. We have matched these criteria for our motherboard design, meaning that F1 through F2 are available on both connectors at each end of the motherboard. See the Wiring Diagram below (wiring diagram is rotated 180 degrees from the orientation shown in this installation documentation):
In this model in particular, F1 and F2 from the connector toward the front are used for the forward ditch lights, allowing for flashing ditch lights, should you so choose. If your model also features rearward-facing ditch lights, these should be connected to F3 and F4 on the connector toward the rear. This will allow you to program them to be directional, and flash.
IMPORTANT NOTE: The locomotive TCS installed had a motor connector which was improperly wired from the factory, with Grey being Positive, and Orange being Negative. To fix this, we re-soldered the connections to the motor. This ensures that the motor direction and directional lighting are all correct when the throttle is set to "forward" and "reverse." Be aware of this possibility - it is suggested to test your model's motor control first before re-assembling it in case this same issue presents itself in your installation.
Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.
TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.
When stripping wire, only strip a tiny little bit of the insulation. Strip no more than a 1/32 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire than 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.
