HO Scale Atlas GP40 prior to installation.
To start off this install, we must first remove the front and rear couplers and their housings. Once that is complete, the shell will lift off of the chassis.
With the shell off, we can now remove the factory light board. First remove any wire clips and disconnect the wires from the board.
Once the wires are loose, the factory light board can easily be unclipped from the motor mount.
Next, we can attach leads to our front 3mm LED and solder the other ends to our AK-MB1
For the installers conveinence, all lighting funtions feature on board current limiting resistors.
Once complete, we can remount the front weight and secure the LED down in the lighting channel.
Make sure to insulate the LED leads from each other as well as the weight.
In our install, we used a 3mm Sunny White LED (Item 1288).
Next, we can attach a SMD LED to the rear light. In our install, we used a Sunny White LED (Item 1417) and glued it to the rear light optic with some CA glue.
Once attached, we can now mount our speaker housing kit.
In order to keep it from rattling and moving around, some double sided tape or CA glue secured it to the ceiling of the locomotives shell.
After attaching the SMD LED to the optic and mounting our UNIV-SH1-C, we can now solder our rear light and speaker leads to the pads on the AK-MB1.
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 Atlas GP40 is now WOWSound equipped and ready to roll!
