TrainsRMe1 Well, I wish I could post a trackplan, but I always have a problem in doing so, I did however used the old method of marking one of my old box cars one side red the other side black, I ran it all around my layout to( get this) only find that every single feeder matched the side of the box car!!! So I guess the only thing to do now is ( sigh) start all over, there must be a problem with the bus wire, I checked all of my turnouts, and none of them are causing the short, UUUGGGHHH!!

If I send you a PM with my email address, can you email me with a copy of your track plan so I can post it for you?

gdelmoroCan you post a trak plan please?
Oh my!
I used to think this was a good suggestion until every new pic of the track plan was a different track plan or it would change the orientation 180 degrees and then 90 degrees and upside down and backwards. Be gentle with us.
It still seems like a good idea to label tracks or turnouts so we don't have to refer to the turnout 1/3 of the way down on the left half of the pic.

gdelmoro Well Rich, sometimes us DCC newbies can FIND ways to short things out. I had all my red feeders connected to red bus and black to black and had a short when I initially installed the system. Seems I had a red wire connected to what should have been a black rail and a black wire connected to what should have been a red rail

Seems I had a red wire connected to what should have been a black rail and a black wire connected to what should have been a red rail I found it using the MR trick of taking an old freight car and painting ome side red and the other black and when I ran it arround suddenly THERE it was! i kept that little car on the tracks as i continued to wire both loops. Also how I confirmed where reverse loops were.

TrainsRMe1 I had to mismatch my bus wire, which I should not have to Do,

.....................unless....................
...........you connected a red or black feeder to the wrong rail.
That's probably what you did, or someone else suggested, you created a reversing section.
I'm at work now, but I could do so tonight.
TrainsRMe1 I have checked every single feeder, they all match up, as soon as I match up the bus wires the short starts.

If you are certain that every single feeder is wired correctly, then something else is shorting the system. Had you ever had the layout running without a short?
Can you post a trak plan please?
I suspect your crossover has created a reverse loop.
To find out, draw your track plan with both rails showing, one in red and one in black. If the red and black lines connect to each other at any point you have created a reverse loop which is causing your short.

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
Well, I do have a crossover just beyond where my short happened in my bus wire. Hmmmmm
Looks like you'll have to start disconnecting feeders until the short goes away. If you have a DMM with a continuity function you can just use the audible signal to tell when you find the culprit.
Check turnouts, as you might have a frog that is bridging A to B and needs to be isolated first. Or you have a reverse loop that is bringing A to the B rail. Just do a visual inspection before you start cutting wires. That way you might find a place to start disconnecting wires.
undo the last thing(s) you did just before the problem occurred.
when desperate, divide and conquer. break bus and track in half and repeat on the half with the short
best of luck

Hi All,
I'll just get to the point, this problem is just crazy!!! I have a short ""somewhere" in my wiring , I had to cross my bus wires (black to red, red to black)my bus wires are Red for the A Track, Black for the B track, my feeders are the same, I have checked every single feeder, they all match up, as soon as I match up the bus wires the short starts. (???????) Help!
