Strange behavior

When you attempt to program the ID, does the headlight blink with the switch in either position?

You do realize you have to set the ID individually on each of the three units for them to properly function, right?  Each of them have a PGM/RUN switch.

I programmed the B unit to change the factory ID from #1 to #42.  All went well.  Then tried to do the same with the A unit.  The light did blink like it was supposed to, but only after I put the Program/Run switch in the the Run position while going through the programming steps.  Then after moving the switch to the Program position, the unit ran properly in Command mode.  The switch just has to be reversed or the picture in the manual is wrong.

Interesting thing was, now with the transformer set to Conventional and the engine switch set on Program, Conventional mode works like it should also.  Not sure why Conventional mode now works, but am glad it does, not that I will use it that way. 

Thanks, John!  This A-B-A set was produced in 1996. That is the newest Lionel I have with a Pulmor motor and, as everyone has experienced, in conventional mode it runs "rough" with the ZW-L's chopped sine wave just like my post war stuff does.  Do you know if the same is true with newer production with open frame motors?

The switch is probably just in backwards, easy to fix.  I've seen this more than once.

I actually have very little experience with Pulmor motored stuff, other than to fix them.  I have a couple of the little TMCC switchers, the Lionel O Gauge 42 Picatinny Arsenal Switcher and the MS&L Switcher.  I also have the original Phantom set that has the AC motor.

Everything else I have is DC motors most with cruise control.  They run fine in command mode.

I also  think the R/P switch might be reversed.  In conventional mode the switch becomes a lock out directional switch when set to program. You mentioned the engine runs  fine in conventional mode when set to program.

I thick I would program the the A&B with the same Engine ID number.

Correct bill, I believe they should all be the same ID for proper operation.

I set the ID for the A and B Units at the same number.  And I will turn the switch around.  Thank you people. 

And the trailing A unit as well.  All three have a RUN/PGM switch from the looks of the parts list.

How many of the units have sound? double horns??

The trailing A unit contains nothing but a headlight bulb holder.

Only the B unit has sound.  

Interesting, I looked up that set on Lionel, and they redirect you to the same set in a different road name.  The set they show has an LXRX board for lights, coupler, and strobe in the trailing B-Unit.

What a bout remote coupler on the trail A?  The LCRX or equivalent would be needed to control directional lighting and coupler.

The LCRX also has a plug for RS support as you state your B unit has.   G

Both the powered and dummy units have magnetic couplers.  The dummy A doesn't have directional lighting.  Here is a picture with the innards exposed.

I have this set and I added a command board , couplers and directional lighting.

See supplement 32 here for your parts break down.

 You can add a Dummy board and coil coupler for for the dummy A for less $35.00  and have direction control of a LED headlight.

It's interesting that a parts search for his model on the Lionel site directs you to a different road name with different parts...

I changed it to Sup 32, that is the correct one. The parts are probably the same only with a different part. For example 600-2028-100 is replaced by a 630-8332-150
