Nov 15, 2020 · LED is an acronym for L ight E mitting D iode. A diode only conducts current in one direction. Which means the LED only lights up when the current is flowing in one direction, and not the other. If you apply DC to the LED and it does not light up, then simply reverse the wires as pointed out above

Jan 16, 2020 · I was wondering about the mixing of AC and DC locomotives in a consist. During prolonged slow-speed/high-current operations, and assuming the DC unit(s) are trailing, how does the engineer in the lead AC unit know and respect the traction motor limitations of the DC unit(s) which cannot endure anywhere near what an AC unit can.

Yes, they all say LM2596. There is also an LM2596T which is more expensive and I'm sure has more functions. You are correct that once I get the regulator set up, it will be a permanent one. I do have a Greenlee multimeter. Thanks

It depends on the brand of track and how it is installed/wired. Traditional three rail track has both outside rails electrically connected to each other, so that would subject your DC power supply to a short circuit. Check that first. If the outside rails are not electrically connected to each other, your scheme will be fine. Gargraves and maybe Atlas have all three rails isolated, but it ...

Aug 25, 2022 · Recently I have been working with my 2 trains on 1 track systems, with blocks and relays. I fixed non operation when both sensor tracks lacked an insulator pin when assembling the train board on installation in the train room and with NO on the tracks, operation is the best ever. I have also finished reading A C Gilbert's autobiography "The Man Who Lives in Paradise". It is …

Not quite, this is what I had in mind. Sorry for the scribble drawing.

Jul 17, 2024 · A number of years ago I saw a wiring diagram for an AC to DC conversion circuit using a bridge rectifier in one of the Train Magazines, using 2 SPDT toggle switches one for AC to DC selection and the other toggle switch for Forward and Reverse selection on the DC side. I have broken wires on my unit and am not sure how to rewire. Does anyone have a wiring …

In practical reality there is no difference when you are talking an incandescent bulb, they work equally as well with DC or AC, to get the same amount of light out of the bulb you use the same voltage/power. People have theorized that DC will extend the life of the bulb because A/C is constantly changing its direction and that "wears out" the filament (I suspect some of this went …

Feb 2, 2018 · The other thread was closed before I could get under the table and measure it. I am using a regulated power supply at 4.5 Volts DC output. The ammeter shows about 0.7 amps dc. It varies a little with the sign blinking, but that's the maximum.

Thanks Dale. I may fit a capacitor in the next time I service the loco. Bert
