I am having a problem with my sounds on my Lionel Class A

Did you replace the sensor on both the engine and the tender?

There might be a bad connection on one of the sensor connectors where it plugs into the pcb.

The tender works with another engine with no problem.

Does the engine work with a different tender

Yes it does.

IF the engine works with a different tender and the tender works with a different engine the only thing left is how the two align when together?  How does the tender to engine connection line up?  G

Re-reading the original post, it's not clear to me what sort of electronics are in the loco vs. what is in the tender. I agree that a physical mis-alignment of the I/R tether is the simplest explanation, given both the loco and the tender are reported to work properly when paired with other equipment.

But it also is possible that there is an incompatibility in the data stream between the two. Was there any change to the electronics in either the loco or the tender that happened just before the sound stopped working?

Interesting. As the engine works fine coupled with another tender and the tender works fine attached to a different engine, how would the data stream rather than some type of misalignment cause this?

Is there a RS/SS switch on either that needs to be switched back to RS from SS?

Any tender paired with the engine doesn't work.

I'm confused here Scott.

If the tender works with any engine we'll say that is good. Not sure from the replies if the engine actually works with other tenders. If no, it does not work with other tenders at all, leaning towards an engine issue having to do with the EOB or connections.

Because not all locomotives are compatible with all tenders. Lionel has been making TMCC and Legacy steam locomotives since the 1990's, not all are interchangeable. For example, you can't combine a TMCC engine and Legacy tender and expect they will work. That's why I asked about which electronics were present in the loco and tender.

Sounds like you're talking about a locomotive problem.  Have you checked with a digital camera or smart phone camera to see if you see a purple glow coming from the locomotive tether LED?  If you don't see anything, that's probably why you have no coupling.

We are not getting the light and I have replaced the infra-red light.

What's the exact Lionel product number for this locomotive?

Either it is wired wrong, or a bad sensor.  Was this the 2 wire or 3 wire sensor?  G

GRJ: I suspect Scott has Lionel # 28052 - one of my favorite locos as well. You can hear the sound system 'down the block" from your house....

That I understood, thought you were referring to a data stream issue a user could correct or fix.
