I just installed a Tsunami in my Bachmann 2-8-0. I used the conversion plug to plug the decoder into the circuit board in the tender. I placed the engine on my programing track and set the address. I then moved the engine to the main and switched on the power. The headlight came on and what I believe is the exhaust sound came on. I then tried to select a whistle when I tried to hear it I had to put my ear about 1" from the speaker (the tender shell was not on) anyway I could hardly hear it, same for the bell. I tried to adjust the exhaust volume nothing happened. When I lowered the master volume the exhaust sound level decreased I tried to increase both bell and whistle volume with no success. When I ran the engine there was no exhaust chuff noise only the straight exhaust sound ( a steady hissing sound). I tried adjust all the various sounds and nothing changed with the exception of the master volume, but of course that only effected the exhaust sound which I can adjust from no sound to very loud. Any ideas as to what I should do or should I just try returning it?
