Hi Folks,
The sound stopped working on my N&W Class A (Lionel 6-28052). The engine has TMCC. When I put the engine on the track with TMCC applied the tender starts making sounds as if it is in conventional mode. The whistle and bell buttons on the Cab-1 do not work. I reset the engine several times per Lionel's instructions in the manual with no results.
I connected the tender behind another TMCC engine. The sound in the N&W tender worked perfectly behind this engine. I also put the other engine's tender behind the Class A. The other engine's tender exhibited the same problems as the N&W tender when it is connected to the Class A. It works perfectly behind its own engine.
The Class A does respond to speed and direction TMCC controls. I found that I could run it without its tender.
I have concluded, perhaps incorrectly, that there is nothing wrong with the sound system in the N&W tender since it works when connected to other TMCC engines. I feel that the TMCC signal is not being transmitted from the engine's TMCC boards through the wireless tether to the tender.
After several hours and much frustration I was able to remove the boiler from the frame on the A's engine. I hope that I can get this model back together. That will be another story. I may need 5 hands.
I don't see anything that is obviously wrong with the boards or wiring inside the engine. I don't have the capability or knowledge to test the boards.
I was wondering if any of you has a suggestion on what I can look for to fix this engine.
I realize that I may just have to send it to a Lionel repair person if I can find someone. I live in the SF Bay Area, CA.
Thanks for any suggestions or help that you can give me. Joe
