Re: Smail question

I am not running sound locos. My layout is N Scale and all of my locos only have basic DCC in them. So far they run great. I have accidentally shorted one of the hidden tracks while my son was running a freight on the front side. The track that shorted was Power Segment #1 and he was running on Power Segment #2. I have used this DCC Power Pack and PM42 on three different N Scale layouts with NO problems.

Joann,

not 'recover' from a short when you have more than one loco or a lighted

sound decoders were first available - and it has not been updated since!

Re: Question about placement and wiring for auto reverser

Drew Aldridge
 

I compared what I had done, and confirmed I did it the same way you suggested, using the switch area as the reverse section. I did this, because as my layout plan shows, i have a second loop on the outside that the switches connect to. Thank you for your website, this helped alot. It helped confirm correct wiring and led me to the switches being my shorting problem.

Unfortunately the thread topic has been changed to something completely unrelated now. I hope that Art, the original poster's question was answered with the direction to your website, as easily as mine.

I am building my version of the NMR Magazine Red Oak Line. I am using a PM42 to split the layout into four Power Sections. The Red dashes show where I have plastic Rail Joiners to separate the four districts.

DCC tools ...

Jeff Johnston
 

Hi, if this post isn't in keeping with the theme of this list, no worries of you take it down.

I'm in the midst of upgrading several brass steam locomotives from straight DCC to full sound DCC with Keep Alive/CurrentKeeper devices. The Keep Alive parts are new to me -- I'm a bit late to get into the game and am excited about the possibilities -- so I cut out styrofoam sample pieces sized to match the Soundtraxx and TCS keep alive offerings (Jeff Johnston DCC tools album, Photo folder, photo 1). I use these when making my initial assessment of what can fit inside my often-compact logging steam locos. Very handy tools.

I always test my decoders before installation and several times later as the work progresses. While I don't use the decoder lighting features all I'm concerned with is the motor drive and sound. To conveniently test these I slapped together the test unit shown in Photo #2. The micro alligator clips hot-glued to the base secure the decoder wires and avoid any shorting problems with unwanted contacts, and the paper "fan" on the quiet-running motor shows me what's going on with that component.

I realize several companies make RTR decoder testers that work very well, and have a ream of extra features (that I don't need). The unit as shown does everything I need and was really low-cost to build. It's another handy device I'll be consistently using.

Re: Question about placement and wiring for auto reverser

Jim Betz
 

Chuck,
  Leave the wall wart for the PowerCab plugged into the 110.  Pull it
out of the powercabpanel and measure the DC voltage from the inside
of the barrel to the outside.  If that is zero you have some sort of 
problem with the power supply - if not you need to check the rest
of the connections - everywhere, one at a time, working from the
power supply plug towards the PowerCab itself.
  Unplug each 'leg' and check power as you go.  Do NOT attempt to
measure the output of the powercabpanel by sticking the meter
probes into the plug - find and use the contacts on the backside of
the plug (it is far too easy to cause the feelers to misalign if you push
meter probes into it).
  Look inside the PCP plug socket - where the PowerCab is plugged
into it and check if the feelers are all straight and not touching each
other and parallel to each other. 

  There are ways that either the PCP or the PowerCab itself can have
a broken solder joint "inside" of them.  I'm not the guy to tell you if/how
to fix those your self.

Smail question

JoAnn Donaldson
 

My Layout is based on the NMR Magazine Red Oak Line. I subdivided it into 4 power groups using an PM42. Each group is isolated using insulated plastic rail joiners. My lay has two hidden tracks and two working tracks. This way if someone is assembling cars on the hidden track and accidentally shorts the tracks, it doesn't interfere with the running tracks. All four tracks show the same voltage level.  I have attached a drawing showing my layout. The Red marks are the insulated plastic rail joiners. I also including a picture of my Digitrax Control Setup. You can see the Wire Bundle come off the PM42 in the middle with two going to the front and two to the back of the layout.
