HO-Scale Athearn SD45 prior to WOW121-Diesel Decoder and RTR-MB1 installation
To begin this installation, first remove the coupler box screws and coupler boxes as shown above. Once that is complete, the shell will lift off of the chassis.
Do this by holding the fuel tank with one hand and lifting the shell off by pressing up underneath the end platforms with your other hand.
With the shell removed, remove the wire connections and then remove original lighting board from the chassis. Mount the RTR-MB1 onto the motor mount in it's place. Remove the rear weight to allow space for the new speaker housing. Save the screws from the weight and re use them to mount the speaker enclosure.
Trim, tin and lengthen the wires as necessary.
Solder the track and motor leads to the RTR-MB1. Insert the 35mm x 16mm speaker securely in to the GEN-SH1 enclosure and using the original weight screws, mount this onto
the chassis as shown above.
Solder the speaker wire leads to the motherboard.
Attach the lighting leads to the front and rear headlight pads on the RTR-MB1 according to your included wiring diagram. For the installers convenience,
the forward and reverse headlight pads are already setup for 1.5v bulbs that Athearn uses. If you require a 12v supply, please follow the RTR-MB1's instruction
manual on how to do so.
You can now plug in your WOW121 decoder.
We can now close up the locomotive, reinstall the coupler assemblies and your TCS WOW121-Diesel Decoder equipped Athearn SD45 is ready to roll!.
