Before I do a repair video on stuff I'm not to certain of, I will comb the internet and collect information. I came across this video made by Ed at his KZread channel "TheCreativeMind" and he had the BEST procedure for servicing the reversing unit. His channel taught me how to do the servicing I did to my reversing unit in this video. Ed also goes in depth on diagnosing the actual coil / transformer portion and explains how it does what it does. I have included a link to his video here. kzread.info/dash/bejne/o4SOsMN6g6jFnNo.html. Thanks Ed for teaching me how to rebuild these ZW's 🙂

I may be mistaken, but the small voltage leak is there to keep the electronic reverse unit from cycling into nuetral when you stop the train. That way when you start the train back up you don’t need to run through the Nuetral, reverse,nuetral, to forward again. I know the American Flyer transformers were made this way. In order to cycle an American Flyer reverse unit you have to raise the dead man handles to cycle the reverse unit. This feature is on the larger 15B transformers and up. Hope this helps a little.

These transformers are really beautiful and made to last!

But it looked like you had a bunch of fun rebuilding & updating that old 1940's vintage Lionel Transformer, boy they made them to last too, comparing those oldies to today's newer stuff there is no competition, the newer stuff if it stops working toss it, the old stuff you can fix it.

The new transformers will probably not make it to seventy years old like the ZWs have and end up as expensive paperweights. 😂

Oh Yeah very well done video. I had that transformer or one like it. I loved be cause I could control 4 engines at once. I sold it. Sadly. Then a Fellow in New Jersey contacted me. He had the Flyer dual control with Volt meters a real beauty. He had bought on line and like yours it was broken in shipping. I agreed to try to fix, it. He was a real nice fella . I had rebuilt 3 Flyer Switchers he had and gave the rusty one for helping. I get the transformer to find one side was crushed from the top. the handle was cracked at the lower pivot boss and the maih housing was broken off at the support for the pivot, it was a real mess. But the unit looks brand new. At the time i had a tiny hobby 3D Printer and I had been making train parts but only small ones. He said was not in a hurry and did not the money to pay anyway so take my time. Nearly a year later I was able to get a new bigger better 3D Printer and now had the tool to print his parts. I ground the handle pivot to a straight line angle then printed a pair part to match the shape and super glued it in. It perfectly matched the other handle. Now the housing. I was going to donate the housing from my dual control, but it did not have those Volt meters. I hated to take mine apart cut it up when his was in such a good shape. So i decided to remake the entire lower part and screw it into the housing as neatly as I could. So the round heads could be seen but were polished stainless and looked very good. I reassembled the transformer and it all worked great. So if you get a Flyer Dually let me know i have the housings pivot frame for the handles, if you need one.

We do not want to breath it in, nor contaminate your workplace, or your home. I wouldn't be working on it with my Lunch or Coffee Cup near by. Be reasonable, responsible, and safe. Collect used solder and store it in a covered container. Clean up the workbench often. If you are generating dust we wear a mask. After a lifetime we might collect enough used Solder to drop it off at our local Hazardous Waste Collection site.

Don't go in straight like I did, drill out the rivet at an angle and the rivet snaps off on the inside of the casing. I learned this while doing my second ZW. Grinding off the studs can cut into the brass bar possibly affecting the current flow and heating up the bar. The terminal can heat up and loosen over time due to thermal differences in operation. Also tightening the new terminal nut does dig into the brass bar.

An AC transformer would require a bridge rectifier to run most HO scale. Of course, then there's still the issue of maximum voltage output. ZWs put out a maximum of about 20 volts, which is too high to safely use with HO equipment. Then, even if you do install or make a bridge rectifier (Simple to make, just four rectifier diodes together) you still need to install a double pole double throw toggle to reverse your DC powered HO locos. So in the end, it can be done, but it requires so much work that unless you have a specific reason, it's simpler to buy an HO power pack.

@modelrailpreservation

Жыл бұрын

I should add, my HO layout does use 1970s Lionel train set transformers, but I did have a specific reason for this. Given the sheer number of locos I run, and they are old (1930s to 1960s) open frame motor units, I divided up my layout into power zones. One transformer for an industrial belt line, one for a yard, one for a roundhouse and engine shop, and so on. Since I do a lot of switching I already use DPDT toggles to reverse blocks of track. So between power needs, and dividing up power means seperate throttles, and the fact I had these transformers laying around anyway, it's worked well for me. Again, though, my needs were very specific, and overall the vast majority of people are just better off with a ready to use HO power pack.

what will you charge to do mine !! seriously ??

I'm not really set up to that. The shipping back and forth would probably run around hundred bucks. The parts were close to $40 and I had 3-4 hours into doing this. If you were local to me it would be a different story. Theres guys on the e-bay that sell reconditioned ones, you send them in yours and they send out a fixed one back. I think I saw $300....maybe......

Why the heck didn't you show the main soldering steps for those of us that don't have or don't read schematics? The rest of the presentation was great except for the important wire connections and routing for the diodes and the circuit breaker.

I removed one wire at a time, and then soldered in the exact same replacement wire, one at a time. I suppose I should have mentioned that in the video. The process took me probably 2 hours, and I did not want to bore viewers with this. I did provide an image of the schematic, said it was online, and I also posted it on my FB page. This kind of update is a medium level electrical repair. Schematic knowledge and soldering knowledge, should be well established before attempting this. I am hoping this answered your question without me coming off the wrong way :-)

@@classicmodeltrains Thanks. I saw another vid about changing to diodes. It was not near as good as your vid and the diodes change was badly done. I was hoping yours would be more informative, but then you skipped over that part and the install of the new circuit breaker. I have 3 ZWs to do, so I was most interested in those parts. Otherwise, your vid was great.

@@michaelragan5799 The diode swap out just involved soldering the one wire that goes to the center post. the diode is grounded from the metal frame it sits on. The old circuit breaker has 2 wires going to it, but they are a little short. I extended the new wires I soldered in to accommodate for the new location. The schematic is just like a road map. Shows you were the wires start and stop. If you number the old wires, and locate them on the schematic, draw colored marker lines to help out following them. Take lots of pictures or video of the before you take it apart. All the wires look like there is a lot going on, but its just the same thing twice. I would not take apart the reversing switch like I did unless you can visibly tell the contacts are very corroded. If you believe the original wires are in good shape, then you really don't have to replace them. Make sure the fish paper is not oil soaked, or else it will conduct electricity. I hope this info might be helpfull for ya.

You spent all that time rebuilding that unit, but kept that old resistor.

The resistor tested fine. This was a upgrade. New parts that were installed were upgraded components. The original components still functioned, But the new installed components were a better choice. Why would it be necessary to replace a resistor that's functioning and no "upgraded" resistors are available? These are my reasons behind what I do. Other people may have different outcomes. Thanks for watching and commenting :-)

I would have replaced the resister too. The problem with electronics is heat and age. As the part heats up the molecules within the part move around more. Believe it or not metal molecules move, just really really slowly. Semiconductors and Carbon Resistors all change over time. Eventually the contaminants and doping within the part move around and stick together. This creates an area of higher resistance, which then generates more heat, which then accelerates the process. When the resistance goes up and the area gets larger enough then the part fails. My 2016 Chevy Van had a PCB with Resistive Traces to set the fan speed. Two of the Resistive Traces burned out within two years. Not made like the Resistor in a ZW. Back in the early 2000's I once saw a presentation on Copper molecules that had moved through a layer of nickel and then a layer of Gold causing the contact resistance to go up and the part to the fail. There is a reason that Corporations used to have Material Science Departments. @@classicmodeltrains

lol 😆 this doesn’t look like work for the amateur or the Squamish.
