There should already be a full wave rectifier between the track pick up and the motor so the track cleaning motor will always run in the same direction with either polarity on DC to the track. So add

The Tomix car already has the full wave rectifier and so will run at a blazing speed when on DCC powered track. The N scale voltage should be more like six Volts. So a number of series diodes

DCC is a AC. You could rectify it with a full wave rectifier chip. And then experiment with different resistors in series on the motor side, to get the speed you are looking for. I assume what you are

Putting one diode in series with the motor will probably make it run at half speed.? Trying this out on your bench before opening your track cleaning car. Putting a resistor across the motor will

Again, not that I'm a an expert, but I always thought hat the DCC voltage to the tracks was constant and that if you modify the DCC Rail Voltage, that would affect how ALL the DCC locomotives would

I am looking for a way to modify the DCC RAIL VOLTAGE to DC for the DC motor. NO DECODERS

Not that I'm an expert, but isn't any non-DCC locomotive on a DCC layout operated with the address of 00? Doug WagnerBakersfield CA??In a message dated 9/20/2023 15:09:40 Pacific Daylight Time,

Sorry. Never mind. Read it too diagonally. Ignore!

Lawrence, What's wrong with changing the speeds via the decoder CVs? Wouter wrote:

I want to convert this N scale DC ONLY car to run on DCC. The DCC voltage from my Power Cab is 12.4v. This makes the motor run at high speed as if it were 12VDC. I don't want to tear out the

Hi thanks for the information.when built this pot I did burn up a few leds then added a 470 resistor to it which solved the problem .This pot going to be used for testing leds for brightness.what I

The politically incorrect mnemonic for resister values that I learned in school is:? "Bad Boys Rape Our Young Girls But Violet Gives Willingly" where Bad = Black, Boys = Brown, Rape = Red, Our =

Guys (and I hope ladies), ? ? In the old days we used to use Resistor Substitution Boxes to figure out the necessary resistor. I bult my first in my first rear of high school and have built a few

We ran into these issues on some of the latest control panels I built at the club. We switched to some high efficiency ultrabright LEDs for certain colors. With the 2.2K resistors we'd been using

Decoder outputs usually are rated for 100 mA (1/10 Amp), so aren't likely to be hurt by smaller resistances. At 14V, any resistor of 140 Ohms or more will limit current to 100 mA or less. Check the

Dennis, Especially if you try the pot approach, be sure to put at least a 470 ohm resistor in series with it while you run your test.? This will prevent blowing the LED should you turn your pot all

Hi guys going to try what rick said.I have a pot that will work,it may help ? This my first time doing this ?it’s a new learning curve for me I have ordered ?100 k ?1/4 watt resistors .

Dennis, I have never heard what you mention about too much draw. I use 1/4 watt and have not had any issues. David Klemm Sent from my iPhone 12 PRO ________________________________ Sent: Monday,

From my understanding from 1k or 1000ohms ?resistors and under is drawing to ?much current ,which is could be problematic with decoder boards ?. I have several decoders that are using ?470 - 620
