Lionel Legacy PA forgetting ID

Bryant Dunivan 

1)  Flipped program/Run switch fast back and forth about 30 times.

2) Assigned ID per instructions with the following EXCEPTION:  Don't cycle transformer power on and off during the assigning.  1) Transformer power off 2) Place engine on track with switch in program. 3) Assign ID - DON'T TURN POWER OFF ON TRANSFORMER 4) Flip switch to run mode. 5) Turn engine off with CAB.

From that point I was done with assigning and have had no problem whatsoever for 2 weeks.  I recommend giving that a try before giving up.  I am convinced it is a switch issue.

Hopefully it works for you guys also.

Great helpful post. I sure hope it helps others with this problem. 

I'm on day 6 and did the same thing @Bryant Dunivan 111417 did, but I also sprayed some Electronic Contact Cleaner on my switches.

I haven't had the issue yet and they are running strong.

I tried Bryant's tricks.  Didn't work for me.  1. flipped program/run switch back and forth about 15 times (sorry, my figures got tired), 2. powered down the track, 3. put engine on track, 4. powered up the track, 5. Put PA in program mode, 6. Used the number already assigned to the engine and hit "set." As usually, it fires right up with great sounds.  Checked the front coupler, works fine.  7. Tried flipping the program/run switch back a forth a few times, 8. Turned Engine off with the CAB2. 8. Turned engine on again with the CAB2, 9. Works fine, until, 10. Turned engine off with CAB2, 11. Powered down the track, 12. Powered up the track, 13. Tried to power up the engine, dead as the dodo, as usual.  Last night I sent a message to Lionel's "TalktoUS" center.  Usually they respond by the next morning.  This time, no response.  I have never thought the PA was better looking than an EMD E (Nose too long, body too short for me) but these Lionel PAs do sound great.  But even the great sound is not enough to keep $1,700 worth of bad electronics.

Great Sounds—With one voiced PA and two PBs all running, less than 3' away, the sound is great and you can't hear yourself talk.

When did the Antennas go to two wires and sticky taped to the shell?

Well, Lionel has has the sticky copper tape for an antenna for many, many years, maybe they're going back to their roots.   I've also seen quite a few locomotives with two wires for antennas.

All the radio boards used in RCMC have a two wire connector for the antenna.  Its used on steam engines which have a wire for each handrail eliminating the wire nut. Not sure its needed on plastic engines but it can't hurt.

Pennsy,   That’s interesting because I always felt the same way about E units versus PAs. To me the E8 is so much more elegant than the PA. Apropos of our discussion, I had to return last year’s Legacy E8 four times before I got one that I was satisfied with. It was an ordeal but in the end I have the engine I always wanted. As for the new Alcos, mine actually have many more problems than the ones the people on this thread have. The one problem I don’t have is addressing the engine because on my tiny layout I simply run it as factory setting engine one all the time. At one point I had four different threads running about all the problems with my set. Of course some of the problems were quite minor but I am not good at fixing anything so I always ask for help on the forum, Even though I have had to weather the occasional snide remark. It is well worth it for all the great advice you get. I have managed to reduce all the problems down to just two. In addition to the front coupler, which doesn’t bother me really, and I could fix if I could ever figure out a way to get that little white plug back in without pulling it right out when I put the truck back on, the only real issue left is that occasionally one unit or the other either loses power or signal and start a tug-of-war with its brother. Right now my guess is that it’s a signal loss problem and I will look into improving that situation. But the bottom line is I am keeping them because I know that if necessary Dean at Lionel will make it right. He got me through all the problems with the E8 and now it is my favorite engine and works perfectly all the time. So even though it is extremely frustrating and time-consuming and sometimes drives you crazy, to me it is worth it to have the engine that I want. Just my opinion.

Correct. However my point was does the two wire connection need to have a closed circuit so the locomotive will "see" the TMCC signal. On previous board designs it is not needed and this was usually one wire in previous command diesels. 

Holding On!!!  Dear Jamesrx, just because of your good experience with Dean at Lionel, I am going to hang on.  I have a Lionel E8 and have never had a problem with it.  After one day of working with four new PAs, here is the situation: 1. Started with voiced and powered A unit not holding its programing when track power is cut.  This problem remains.  2. One PB unit was also not holding its programing when track power was cut but started working as specified.  I did nothing to it, it just started working.  3. Second PB always worked as specified.  4. Powered, non-voiced PA unit has always worked as specified.   So overall, I have three of four units working as specified.  5. I hear no difference between the PA versus PB (super bass) sounds in terms of volume or sound quality (horn, engine, crew talk). 6. The PA/PB sound volume and quality is noticeably better than the 2018 Lionel E8 or TMCC.  So far, in my experience, the only sound that could rival these new PAs/PBs, if the vision line GG1, but I have not done a side by side comparison.  I would like to know the experiences of others.

2. One PB unit was also not holding its programing when track power was cut but started working as specified.  I did nothing to it, it just started working.

3. Second PB always worked as specified.

4. Powered, non-voiced PA unit has always worked as specified.  

Pennsyforever- 

Can I clarify a few observations on what you are seeing?

1. Are you saying the lead A unit with sound will not take a unique program ID number and reverts back to 1 every time the power is turned off?

2. Can you confirm this one is taking commands? Or is it just starting up in conventional? Can you change the ID or program?

3. Worked as specified? can program to new ID and will retain new ID and functions properly in command?

4. Worked as specified means; can program to new ID and will retain new ID and functions properly in command?

I would like to compare observations that I am seeing as well.

One wire could break and the antenna would still be functional. The two contacts on the board are wired together. One wire to either or both contacts is sufficient. I am assuming the factory has wired all the antenna connectors with two wires so they can be used for either steam or diesel and then just tie them together on the diesels.

I just opened my RS11 which also has Alzheimers. It too has two wires soldered to the antenna plate.

Dear J DADDY:

1. The lead A unit with sound takes a unique program ID number and works fine, until the power is turned off.  If the power is turned off, I cannot tell you what it reverts to.  All I know is that it will not take a command with the ID assigned.  So I start all over again by reprograming it.

2. Once the track power is cut, the lead A unit with sound will not start up at all if power is returned, until it is reprogramed.  I don't run conventional so I can't tell you what it would do in conventional.

3. The two PB units and the non-voiced A unit are working with the original IDs I programed them with.  I have not tried to program new IDs.  If it aint broke, don't fix has been my approach.  That is, I can power down the track and power up, and they (PBs and non-voiced A) take full commands.

4. One of the PBs with acting like the lead A unit, but the problem went away yesterday on its own.  Since that time, it has been working perfectly.

5. Also, I have not tried them in a lash up.

Thanks Pete.  Than I think what happened to mine was the antenna plate lost its adhesive to the shell and grounded the signal out on the frame . When it was sitting loose inside the unit .

Pop the lids and see if your antenna is floating around in the housing. 

J Daddy, are you telling me to take the body off?  Is that hard to do?  What does the antenna look like?

Pennsyforever

The same TMCC receiver hardware is used in diesel and steam, so it makes sense that it would be optimized for either use. 

Got up this morning, powered the track, Lead A unit fired right up with everything working!!!!  Can't explain it, but nice to have it working.  Next, will try a lash up.

Is this with the new ID number or ID #1? 

Pete

Dear Pete:  Using the same ID I programed when I got the unit, that is, a new ID, not ID#1.  Lash up working, ABBA.

Well, mine worked for about 7 days and then today I had to reprogram both A units, the B unit was fine.
