Question on the Shorting Out Problem
Posted by BNENGR on Saturday, February 23, 2008 12:53 AM

Hello again guys. Thanks so much for all your help. You're a great bunch of guys and I'm so glad I have this group for help. Don't know what I'd do without it.

Question: I hav'nt had the time to try a DCC loco yet on the problem area. First thing tomorrow I'll give it a shot. I have several DCC locos that are ready to go. Why did'nt I try one of them first? Dum! Guess I figured that since Digitrax said you could run DC's I figured it did'nt matter. I did'nt think!!! Well, okay. Let's say after trying the DCC loco, everything works fine. Then........should I reconnect all the feeders that I removed from the bus wires on the new section including the yard. All legs of the yard are double gapped. Also, where should I locate the PSX-AR? Leave it where it is on the problem track #8 in the old section or put it back in the new section on the main by the yard?

As a general rule when using the PSX-AR, should you just use IT for power, or should you use feeders off the bus as well? Sooner or later I'll catch on to all this new DCC stuff.

Thanks so much.

I will tell you what I would do, hopefully clearly enough to understand!

I would create two buses, one for the original section, and one for the new reverseing section.  Reconnect all of the feeders in the old section to that bus for that section, and power it from the command station.  hok up all the feeders in the new section to the bus for the new section, and power that bus from the PSX-AR.  The PSX-AR gets power from the bus in the original section, or the command station (same thing, right?)  So the yard will be connected with feeders to the bus that is powered by the reverser.

I once seen a Diesel truck stuck under a train overpass, the police, the fire dept and the RR super were there scratching heads as to how to get this truck unstuck when a small boy, I would say about five stood up and screamed out "let the air out of the tires you morons".

In short Paulie, We sometimes get so caught up in the problem that we are trying to solve that we can't see what is staring us in the face. I've done it and will do it again.

I moved to Boston for awhile and a local radio station there used to run a contest every fall when school was starting called Big Bucks for Stuck Trucks.  It was for listeners to predict when and where the first student moving to Boston would hit one of he low bridges with a U-Haul, Ryder or similar truck.  The Boston Police Department helped with the watching and reporting.  In speaking with one of the locals who worked for me, he indicated that there are times where the bridges are so low and the trucks were going so fast that he has seen where they have all of the tires flat and they still can't unstick the truck.

In short (no pun intended), you need to all feeder wires going to track located within the reversing section run the one bus.  That bus must then be connected to the output side of the PSX-AR.  Note that there is an input and an output on the PSX-AR.  Getting them backwards will cause problems too.  Connect the input side to the normal track bus.  Simple. Done.  Excluding any of the optional connections there should only be 4 wires connected to the PSX-AR - 2 input, 2 output.

On a separate note, you'll do better if yan can keep everything regarding an issue in one thread.  Responders will be able to view the timeline of events in one thread instead of chasing them down across 4 different ones.  There were clues to your problem in your first post in the first thread, someone reading your third thread may not have seen the first one and picked up on the clues and been able to help.
