I believe Floyd described that he wired his lights using an Atlas Connector, which would mean they are wired in PARALLEL, not in series. Hence his confusion as to why they are blinking... We can all easily understand how a blinker would affect a SERIES circuit, it't the blinking in the...

bclemens is correct, except I had a question in the AC v. DC case. I think this is correct, but please let me know if it's not!!! 18.5 VAC is an RMS measurement (at least if a modern DMM was used). Therefore, that value is only .7071 of the PEAK voltage that occurs at the top (and bottom) of...

I've been thinking about this a bit more, and another way to test the situation would be to put a voltmeter across the power pack output (or right across the input terminals of the connector - same thing). Ideally, that voltage should say about the same (my guess is 12 VAC) as lights are...

Got It!! As it turns out, the Walthers site referred me to a local hobby shop that was out of stock on the book, and they said it would take a few weeks to get if I ordered direct. By pure chance, I was driving somewhere and passed another hobby shop - I stopped in, AND GOT THEIR LAST COPY...

Assuming that you have the power pack connected to the (2) input terminals on the left side of the leftmost connector, and each light is connected to a pair of switched output terminals at the top (I'm guessing you probably have this correct), the only thing I can think of that would cause any...

Can't wait to buy Atlas book Sperandeo did not say if his schematic came directly from Atlas' book, but I find it hard to believe they would be wrong about their own product... Anyway, I greatly appreciate you sending the link - I am going to order Atlas' wiring book right now. BTW I see...

Rocket Surgery, Eh? That's a good one! :) Andrew, you mentioned an "official" schematic - may I ask what are you referring to? I have never seen any schematic of the internals of a Controller, except the incorrect one from Sperandeo's book, and my own. Am I missing something? (it certainly...

Must be a tough question... Wow, still no replies! I actually contacted Andy Sperandeo, the author of the book with the wrong schematic (who happens to be the editor of Model Railroader...), and sent him my schematic which was reverse-engineered based on continuity tests. I am hoping he...

What kind of blinking light? If the light blinks by SHORTING itself out to turn off, I can see that bringing the whole pack voltage down to zero, effectively turning everything else off... That seems like a strange way to cause a blink, but who knows! What kind of blinker is it? Does the...

LED's on AC You should be able to run LED's on AC power as well. As diodes, LED's will allow current to flow in one direction only, so on AC power, they will only light for 1/2 of the AC cycle. The effect is that they light less brightly than they would on DC. Of course, as noted above, be...

I am very curious about the internal wiring of the Atlas #220 controller. I saw a page from a book (page 55 of "Easy Model Railroad Wiring" by Andy Sperandeo, 1999) that showed an internal schematic, but about 10 seconds of testing proved that diagram was WRONG! I have come up with what I...
