Does ANYONE have any "EXPLODED DIAGRAMS of 3 volt and 5 Volt PS 2.0 BOARDS?????

Hello, I am trying to learn a lot more about these fabulous MTH trains that we all know and love!!! I have a deep desire to be able to perform simple repairs for myself,and I have a true passion to learn more about their inner workings. After 37 years,you would think that MTH would have somekind of common repair manual available. But they have kept everything TOP SECRET,exceot for a privileged few people. I want to be able to look at a 3 or 5 volt board,and name the IC components,and know...

ALEX M DOES IT AGAIN!!

The Dude ·
Yesterday I spent some time over at Alex M’s repair shop. In the past he has worked on many of my older TMCC Steam engines for ERR upgrades and repairs. I had asked him if he could look at one of my Lionel diesels, the 6-38182 MKT FA2 from 2003. Normally with diesels I will attempt the repairs but this one was in such bad shape I decided to let Alex have a look at it. Alex disassembled the entire engine right down to the gears in the gear boxes on both trucks. Cleaned all the gears, applied...

Can anyone help me repair a K-Line switch. I broke the frog rail off of the tiny plastic piece off that holds it rail to the moving tie and I am not sure if I can repair it with a small screw or if I need to find the part somewhere?

2065 Repair

noswad ·
Got a 2065 that’s ailing. In Neutral it’s fine, but as soon as it come out of Neutral its a full blown short. It’s a new to me engine. I am beginning to think that maybe the armature is shorted out. What is the best way to test it? Is there an expected resistance that one could check for? I haven’t yanked the e-unit out yet. It’s pretty tight in this model and I don’t want to risk breaking any wires if I can avoid it. Also, do I you have to remove a drive wheel to get the armature out on...

Repair a hollow brass or bronze casting help

BobbyD ·
It is a hollow water tank spout, I don't have it in hand yet, that a friend asked me to paint. It is about 3/8" down to 1/4" with a tiny casting flaw hole in the spout wall and resembles this piece. Would attempting to solder make it worse? JB Weld? Afraid I won't be able to sand it. "Bondo"? It won't move after it is installed, so handling isn't an issue. I don't want to make the problem worse. Thanks!

Cab 1L vs Cab 1 Replacement? Or Maybe repairs?

PR&NJRR ·
I have had my Cab 1 for many years now, I only have the one remote. It is starting to show its age, as at the current point, many of the essential buttons on it have stopped working, no matter how hard I press, namely the Direction button. At this point I have two questions to ask, and I don't expect an answer right away since it's late. 1) Is there a way to fix this remote to restore the buttons to their original working condition? If so, how? 2) If it cannot be fixed, I am considering a...

Lionchief + does not run

DocMcKay ·
I have a defective Lionchief Plus Pacific (Southern). My question is, from anyone's experience, would you advise I return it to Trainworld or ask them or Lionel to repair it? I just received it from Trainworld, the warranty is in effect, and it gets power (some chuff sounds) but does not run, either from transformer or remote. I followed the instructions carefully. My other engines run fine on the same track. 80 watt, 16 volt transformer. Thanks for any suggestion.

Re: Z-4000 Repair

Without a load, the outputs probably show a leakage that is not something that can be eliminated. And when there is a load, the outputs are zero-ish?

Re: Z-4000 Repair

I wouldn't spend any time trying to "fix" stray voltage indications with no load on any variable transformer. If it functions properly with a light load, it's working properly.

First generation Z-4000 were susceptible to voltage leak and there is a modification that can be done to the board using .001uF SMD caps. They are soldered between pins 2 and 3 of U-1, 2, 5, and 6 on control board. G

Re: Z-4000 Repair

Yep, probably a 603 size would be appropriate to fit there. I'm sure 50V or more would be fine as a voltage rating.

OK, the fan is replaced. Several things I learned: There are 6 screws in the bottom of the case that have to be removed. A long T-handle 3 mm Hex key works very well. These are definitely NOT Torx screws. The fan is actually 60mm square, and 18mm thick. The fan is wrapped on the edge with open cell foam. Its not worth trying to reuse it, so having some available is wise. Figure 1/4" thick, and ~1x 10". I used a CPU cooling fan I picked up at my local computer store. The connector is not the...

"They are soldered between pins 2 and 3 of U-1, 2, 5, and 6 on control board." Does this mean U-1, U-2, U-5, U-6? Between pins 2 and 3 of each? So I need 4 caps? Just seeking clarification. Chris LVHR

Re: Z-4000 Repair

Train Doctor ·
When you had the cover off, on the gears that connect the geared wheel on the lever to the gear on the potentiometer have black marks on them which should align when the handle is in the zero position. If they don't, you will never get a less than 1 volt reading on the screen, and may have problems reversing locos with electronic reverse units.

MTH will want the model number of the engine, and picture of the pilot , with step paint scheme. What is a rectifier, I would think several different types, so you need to be specific. They do carry pilots, but may not have exact one, and therefore you might have to paint, like yellow stripes on steps. G

That's a possibility John. I have all of the pieces. I was going to check at Home Depot for some epoxy. Maybe with some very thin pieces of metal, to act as splints, I can do the repair.

I have removed the existing circuitry from the locomotive. I am wiring in an AC-DC converter to take care of the power requirement for the DC motors. I would like to get a hold of a Williams by Bachmann reverse unit or perhaps a Dallee electronic E-Unit. If anyone has one they would like to part with please send me an email. One question, however, is this. Would the new E-unit/Reverse unit get wired into the circuit on the supply side of the AC-DC converter or on the "Out" DC side ?

Re: MTH Rectifier Loco Repairs

gunrunnerjohn ·
The reverse unit replaces all the electronics, no additional AC-DC converter is needed or even wanted. The reverse unit connects directly to track power and to the drive motors. Send me an email if you want a reverse unit, I have several types in my parts box.

You said you would post info about how to take the carousel apart. Did you do that? If so, where can I find it?
Reply

Re: Lemax Repair?

breezinup ·
Getting that Lemax stuff apart is a real bear, I've found. They use a lot of glue to put things together, rather than screws (cheaper assembly process) and extremely fine wires (cheap, again, I suppose), and I've had to practically use a hammer and chisel to get them apart, and then it's easy to break the fine wires or other pieces in the process. I have several dead items lying around to trash - no reasonable way to fix them.

Yes, Just those for micro chips get a cap, and the cap is soldered between the legs (2 and 3). These chips are 8 leg (2x4). The dimple on the chip is pin 1 and pin 2, 3, 4 on same side. G

Luke, On mine, the large gears have a black mark on it about midway in the travel. The small gear on the pot has either a black mark or an arrow molded in the plastic. With the handles about mid point, the marks line up. That's the way I found it, and that's the way I left it. I was tempted to purposely misalign them such that the pot would turn down further, but not knowing all the consequences of such a move, thought that might not be a wise idea. G, Thanks for the information. Chris LVHR

Now that I've tackled most of my engine issues, back to this one. I figured out how to pull the carousel apart (another post on that later). The most obvious issue is seen in the picture below: A broken lead on the speaker. I seems the PC board piece as broken and in the process, severed the connection to the speaker. My question is how to repair this? Glue the board with ACC, and then quickly solder? Remove the broken PCB piece and solder to what is left? There is not a whole lot of surface...
