Today I replaced the speaker and I tested the unit without the tender body on. And I did not mate up the drawbar from the engine to the tender. I had a good whistle and bell sound while operating it in TMCC and remote. I then disconnected everything and put the tender shell on and plugged in the back up light, screwed down the shell reassembled everything correctly, got the engine to move, but no bell, no whistle, and also slight air pump sounds which is fine. The remote couplers fired, but crew talk did not work, like it did without the tender shell. Since I have not been able to hear all the sounds, I don't even know if this engine has any type of exhaust (chugging) sounds, And to add to all these weird situations, when I pressed the whistle button on my MTH 4000, the whistle blew! When I hit the bell button of the transformer, the bell rang. What is up??!! The tender frame also has electrical tape running along the edge of the frame. Would this be causing a problem, if I did not get the tape back correctly, i.e. is the shell making contact with the frame causing problems. Help!
Thanks,
Jeff
