I've got this unit and it won't run. Cleaned the wheels and rollers. In the past, if I had not used it in awhile it would be a slow start...you would have to help it along and then once it got running it was fine. It is one of the first-early TMCC locomotives. It has the program/run switch under the back roof/cab. I'm pretty good at repairing postwar engines, but I know this one has some boards in it. Anybody have this kind of trouble with same or similar unit from early 1990's?

Mark,
If the armature & brushes are clean and you serviced it. I would check the stud for the intermediate & cluster gears. I had two of these engines that did the same thing and it turned out to be the studs came loose in the motor frame and caused the gears to cock and jam.
Hope this helps.

That was one of my favorite engines. The strange thing it sounded so different then the other similiar models. If I remember correct everything was in the tender with a tether
to the engine. The tricky thing was the tether connector. It was very easy to reverse as it wan't keyed. This would fry the lcru. I cooked this thing a night or 2 before christmas. But, was able to repair the LCRU.
Do you have sound? Running conventional/command?

I have sound in the tender. I'm running TMMC & Conventional. Your note on the tether is interesting as I believe I tried it 'both ways'. Hopefully since it was running anyway, I did not cook the LCRU. To bad they did not mark that or make it connect 1 Way....for kids and us : ) Is the LCRU easy to fix or replace? I'm good at repairing Post War engines. How would one know the LCRU was cooked?

Did not clean brushes! Will do that with coffee in the morning. Hopefully, per Shawn, below, I did not cook the LCRU. Even though I tried the tether 'both' ways, it was still dead and not getting power....ie., the engine headlight was off. I off course tested other engines and they run fine in TMCC and Conventional.

Here are the exploded views for the loco and tender. If the loco is dead, check for power at the pink wire connection on the board from the rollers, then the yellow wire to the bulb. If power is coming into the board, but not out, the board is bad. The bulb at least should be on at all times, and under all conditions.
The tender diagram shows the connector plug as "smooth side up", so maybe put a paint mark on it to remember.
Reversing the plug may have damaged the LCRU board; hopefully it did not take out the sound board in the tender also.
