Yes, I am more of a railfan model operator than an operations oriented operator. Let's see what I can find, since my layout building is in disarray right now. My latest, MTH PS3 Western Maryland RSD-5

I noticed that the battery eliminator that Dallee sells does not have the diodes across the caps. You mean I have been going to the trouble for no good reason ? Anyone else out there leaving the diodes off. j

Railfanning from Home

No need to go outside in the cold. Let's do some railfanning in the comfort of our own basements and attics: Leading the charge: Postwar Lackawanna FM Trainmaster and 623 Santa Fe Switcher. Now we can share our railfanning with each other from home. Arnold

Home grown wiring harness and plugs

JohnActon ·
A couple of years ago I was modifying a pair Lionel NYC Alco PA-1 both powered. I wanted to use the electronics from one unit in an early Williams FM Trainmaster since it had Pittman motors and MagnaTraction. I had to modify the heatsink for the DCDR motor driver and open a path on the rear truck for the eight wire harness to exit and pass over the couplers to connect the two units. I used connectors called Dupont connectors which I ordered on eBay. They come with single pin male and female...

After posting this I searched ebay and found that you can indeed buy a kit now with seperate ends and they are available in multiple conductors. This would make the process much easier. These were not available two years ago though I guess I could have missed them. I did search the entire category. Link below is for a kit with connectors with 1, 2, 3, 4, 5, & 6 pin connectors, There are kits with up to 12 pin connectors. You may want to search the category "Dupont Connectors" for a...

I got lost on one point, but assume you mean you doubled up 22g to each terminal...? (mind terminals have max amp ratings too. The spec is in the max wire gauge listed. E.g. For 18-14g handles 14g worth of power. Also, power delivery wire has a lower awg max amps than signal wires (that usually get a break from work via frequency, or power reductions which form signals.) Dupont makes all kinds of good stuff.

Why not use the standard connectors used by Lionel for all their TMCC stuff? They use JST-EH (2.5mm) and JST-PH (2.0mm) for most TMCC stuff, once in a while you'll find the smaller JST-ZH (1.5mm) connectors. Legacy mostly uses JST-ZH and Molex PicoBlade (1.25mm), though there is still some JST-PH connectors in some models. You can get all of this stuff from Digikey, and I use the Engineer PA-09 or IWS-2820M AWG 28-20 crimp tool, both available on Amazon.

Re: Home grown wiring harness and plugs

Did not double up any single conductor I did substitute 22g on two connectors one for power and one for chassis ground. I think I also put 22g on the motor leads ? All the other wires were the stock 28~30g. Can't imagine ever needing 14awg for a harness between to O gauge locos. I think what threw you off was the part where I pulled off two strands of four then reversed the ends so there is a M & F connector on each end once they are glued together. I staggared them when gluing together...

John, I put JST plugs on the end of the harness inside the loco at the boards. I bought 1000 pins and 100 each 2, 3, 4 & 5 conductor plugs when I first started converting my conventional loco collection. I have been buying used boards both TMCC and PS2 and 3 usually they come with a bunch of plugs if not a complete harness so I haven't had to make any 2 or 3 pin plugs but have made some 4 and 5 pin. I don't have a crimp tool however and have been soldering the pins on. Since I don't do...

I can't use the viewer here & that pic is too small or to low a resolution. No biggie. 22g strikes me as lite for power deliv livery; that'st allhat. It's about 4a max for power delivery, but I guess maybe with chopped waves your running cooler anyhow. . I get "polarized", we always said "keyed". I took to slices for keyways on the male end and cutting bands on the females melt/benting my own keys once. I like to use plugs with the ability to add a female pin among males and visa versa...

Footnote: Lionel harnesses use 105-degree insulation (Centigrade, IIRC). Yes, I know that's the old name; try Celcius, which the site tells me I have misspelled, or... . Most of your amperage/wire gage tables will be based on some other temperature rating. Then your ambient temperature is a factor-- few have belonged to a club in a 105-degree (Fahrenheit) space. Some useful relationships for the logarithmic AWG series: 3 gage numbers lower will double the copper area, but 4 gage numbers (as...

If your locomotive is drawing 4 amps, there's something wrong with it! Also remember, the #22 will carry a lot more than 4A long enough to trip the breaker.

John, the 330/35v cap. That's just a common electrolytic, not a low ESR ? All I can see on mine is the 330uf and 35v. The other marking are facing the center of the board and I just can't make them out. j

I just used a standard cap for the 330uf cap, it's not anything special. The key requirement is the size and lead spacing.

The 9V battery eliminator probably should have the diodes to balance the charge. OTOH, the 3V one using a 5V supercap needs no diodes, just the supercap. I've done dozens of these, they plug right into the PS/2 power board and you can eliminate the charging harness. When I do upgrades, I supply one of these to avoid having the extra hole in the tender that I have to drill and shape for the square connector.

That's what I was thinking but guess they have a different plan. Can't imaging Dallee did not try it the way they show and I do hate soldering those tiny zeners on, may try and make one without them. I developed a tremor in my hands a year or so ago and over half the time to make them is soldering on the zeners. Let you know if it fries something. j

Re: HOME BREW BATTERY SUBSTITUTE

gunrunnerjohn ·
If the two caps are identical, you will probably be OK, though there's no certainty. The issue that the Zener diodes address is uneven charging, that happens if the capacitors are not well matched. I doubt you'll fry anything, but if one of the capacitors see more than about 5.4 volts, they will likely fail in a fairly short time. Note that those individual packages actually have two round 2.7V capacitors in them, and they're in constant use all over the world, so I suspect the caps are...

I know about matching caps. I did product and industrial photography for years and had some big strobe packs. When the caps in those strobe packs blew it was like a firecracker going off. When one cap blew I would buy eight new caps and insist they were all from the same mfg lot. Even then you had to make sure they were fully formed before you put them in the circuit. If you did not have them in an identical state the weak one would blow taking the diode bridge with it. I forget how many...

My method is to heat the closest lead to the edge and rock the cap as far away from me as possible, then do the other lead. A couple of passes like this and the cap is out. I clean out the holes and solder the cap in. In order to give myself as much space as possible I "spring" the boards as far apart as I can without breaking something, that allows me to slip the soldering iron tip in and get to that cap. I've done at least half a dozen of these, a couple were malfunctioning, but not...

Thanks John, eight MTH locos four with PS1 and four with 5v PS2 boards Wish I could afford to put all new ERR boards in all of them but that ain't gonna happen $ So, the plan is to add BCRs and new 330uf caps to all the PS2 5v boards. UCUBs in three PS1 and I have two PS2 3v boards and slaves for an AA centipede and an ABA F3 if I can sort that slave thing out. This will take me through the first of the year at the rate I work. j

GunrunnerJohn, your video of the Horseshoe Curve reminds me of fishing. You may have to wait a very long time before anything thrilling happens. That's one reason I fished for a very short time and stopped 20 years ago. I think I prefer Railfanning from home more than Railfanning with real trains.
