Bachmann 2-8-0 Tsunami Digital Sound Decoder Installation Notes Overview This application note describes how to install a TSU-1000 digital sound decoder into an HO Bachmann 2-8-0. Skill Level 2: The entire installation can be completed in one to two hours with no modification required to the model. Bill of Materials P.N. Description 826104 810054 810119 TSU-1000 for K-Class 28mm (1”) dia. Speaker 28mm (1”) dia. Speaker Gasket Kit Tools You Will Need ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ 25W Soldering Iron Rosin Core Solder Electronics Solder Flux Wire Strippers Wire Cutters Hobby Knife Miniature Screwdriver Set Toothpick Small Pliers Double-sided Tape Installation 1. Disconnect the locomotive from the tender by carefully separating the two plugs that connect them together. Set the locomotive aside. (Photo 1) 5. Attach the 28mm gasket to the 28mm speaker by peeling off one side of the backing. Be careful not to get it on the cone. 6. Peel off the backing on the other side of the gasket and press the speaker into the baffle. Note: make sure the solder pads for the wire are facing toward the rear of the tender. (Photo 7) Photo 1 2. Remove the screw located under the front truck and gently lift off the shell. Note: there are two tabs on the back of the shell that help secure it in place. (Photos 2 and 3) Photo 7 7. Reinstall the factory PCB over the speaker. 8. Measure and cut the Tsunami wires to approximately 3” in length. (Photo 8) Photo 2 Photo 3 3. Unplug and discard the DCC mobile decoder to expose the NMRA 8-pin plug. (Photo 4) Photo 8 9. Cut the speaker wires to approximately 5” long. 10. Strip 1/8” of insulation off the ends of each wire and tin the ends for easy installation. Photo 4 4. Unscrew the two screws from the factory PCB to access the area for the speaker. (Photos 5 and 6) Photo 5 Photo 6 11. Using a toothpick, place a small amount of solder flux into each of the 8 pins in the NMRA 8-pin plug. 12. Begin soldering the wires directly to the NMRA plug. Start with the orange wire in the upper right-hand corner (engineer side) and push the end of the wire into the corresponding hole. (Photo 9) 15. Attach one 1” piece and one 1/2” piece of double-sided tape to the tender shell to mount the decoder and capacitor. (Photo 11) Photo 11 Photo 9 13. Working right to left, complete wiring the wires to the NMRA 8-pin plug. See Figure 1 for the pin arrangement (orange = Pin 1). (Figure 1) Figure 1 16. Attach the decoder and capacitor to the double-sided tape. Note: the brown, green, and off-white wires are not used. These can either be cut off or secured with tape to prevent issues later. (Photo 12) Photo 12 14. Solder the speaker wires to the speaker solder tabs. Note: because we are using only one speaker, polarity doesn’t matter. (Photo 10) 17. Place the tender on track to test the installation. If all is well, the red light should appear on the decoder and sound should be controllable on Address 3. 18. Reattach the tender shell and screw the tender back to body to complete the install. Then plug the tender and locomotive back together. Let the fun begin!
