Lionel TMCC 4-4-2 Atlantic issue help (

Probably a stupid question, but did you put the run/program in program, and remember to turn it back?

Command would be:

Engine, 1 (or any #), set button,

Engine, 1 (or any #), Aux 1 button, 4 button.

Whistle should blow after each command is completed.

Lots of things to check here, besides the basics Chuck mentioned.  If absolutely no lights on engine, is it getting power?  May have a loose connector, or boards.  Your going to need to open it and inspect.  If your not comfortable, need to take it to a LHS Repair tech. G

If the sounds come up immediately when you power up, and there are no lights of any kind on the locomotive, it sounds like the locomotive is not getting power, and the tender is coming up in conventional mode.  If you're comfortable taking the boiler shell off, there could be a loose wire or connector.  If not, I'd follow George's suggestion and take it to a repair guy.

Ok I removed the boiler shell and found that the board had become loose. I re-attached the board and tested the engine and it did run fine. Problem is I only have firebox glow and no other lights are working. Marker lights and locomotive headlight are off.  What would cause the lights not work?  Any help appreciated.

Try pressing AUX2 on the remote before any additional steps.

I placed the engine on the track in program mode and enter Aux 2. Firebox glow still working and I have the marker lights on the tender working but only in reverse.  Is there anything else I should try or look for?  Also the smoke unit wick material is dried up.   Can i follow the lionel on line smoke unit refurbish video to repair the smoke unit on this engine?

Don't place in program mode. Put back in run then try again, Aux. 2 turns the headlight/back-up light on and off. If it still doesn't work, probably a bad bulb.

Thanks Chuck looks like I need a new bulb or two.

The other possibility is that you had a short to the frame with one of the lighting leads and the R2LC triac was toasted.  Before you go replacing bulbs, make SURE no wiring is shorted and then swap an R2LC from another engine to see if that lights the lights.  Multiple bulbs all going out doesn't sound as likely as taking out one component on the R2LC.

Loose R2LC.  If it has sound, that tells you the engine is not getting TMCC signal.  The RS audio and power board are controlled by the tender rollers.   Check the R2LC and make sure the handrails have no continuity to the locomotive body.  It is not seeing the signal.   Sounds easy to fix.

Marty, he plugged the board in and has command operation, he just doesn't have lights now.  His initial issue sounds like the board was loose as you suggest.

I am sure a reprogram will bring the lights back.

still just getting fiebox glow only so I am going to replace the bulbs.  thanks for the response.

Why not test one or all of the bulbs before replacing them.  Multiple bulbs out suggests to me that the R2LC output isn't working.  I believe the firebox glow is directly to track power, so it stands to reason it would still be working.

Ok so I will test the bulbs. If I need to replace the board is it still available from lionel?

Yes, the R2LC is readily available.  If it's just the lighting triac, it can also be replaced for less money.

John

Don't see a lighting triac on the lionel web site ,I see the R2lc board only listed under the 4-4-2 E6 Atlantic TMCC.

It is a component level repair on your R2LC.  It is a MAC-97 Triac. G

Thank you but the MAC-97 Triac .G  . I tired it on the Lionel repair parts web site getting no results.

What he is saying that ...there is a bad component on the board. It can be replace rather cheaply if you know someone that can desolder/ solder. The part is available via online....there are not many local parts houses. So, you get the component do a board level repair. Or buy the whole board.

Thank you for the clarification, probably just buy a new board.

I buy those at Mouser, they're dirt cheap.  They have them at 45 cents.

John, those boards are so cheap, I would rather use a new board instead of the repair.  What you point out is very easy to do.  I have done it when I do not have the right R2 code to use.  

Marty, I repair the R2LC if it's just a triac, pretty much anything else I replace it.

Thanks for the responses. I purchased a new R2LC and lamps and now lighting woks and running fine.

The smoke unit is not working and I cant find anything showing how to repair the older style smoke units that this engine has. Would I be better off just replacing the entire smoke unit?  I tried shoving in new batting and that did nothing,

Is the smoke resistor getting hot?  Is the smoke switch on?  Have you done a reset of the R2LC using the code AUX1-4?
