Shorting out
mecmt:
Thanks for the help Alan. I understand the resistor with the wiring diagram. So lets discuss the power pack. Would I use this in place of the PWR-56. I am thinking I would. Do they come with a diagram on how to wire it up.
Alan:
Easy peasy. The power supply will have screw connections for 115 AC in and + - 15V DC out.
Here is a pic I found on the web. It is typical of the connectors found on almost all made in China power supplies.
Do not do any wiring with a cord plugged into a wall socket!!!
The 'L' stands for line and is where you connect the black wire of an AC power cord. The black wire is the narrow blade on the plug.
The 'N' stands for neutral and is where you connect the white wire of an AC power cord. The white wire is the wide blade on the plug.
The ground symbol is where you connect the green wire of an AC power cord. The green wire is the round 3rd pin on the plug.
Each of the above are high voltage house current. Cover the connections so they can never be accidentally touched or shorted together. The shock will knock your butt across the room. Use a 3 prong AC plug. Do not use a 2 prong AC plug.
The 'COM' stands for common. It is often referred to as DC ground or zero DC volts (not to be confused with the ground symbol on the 115V input). COM is the same as the black wire of a PWR56.
The +V terminals are the 15 volt positive output. +V is the same as the red wire of a PWR56.
The two COMs are tied together inside the enclosure. +V1 and +V2 are tied together inside the enclosure. It doesn't matter which you pick. They are the same. Two connections for output are provided for convenience since these power supplies are often used to power more than one device.
Alan:
Before you buy a power supply or even before you make a switch/resistor circuit, make sure you don't actually have a short circuit on your layout.
Take all rolling stock off the rails. Turn on the PWR56. Add rolling stock to the rails one at a time until all cars and locos are on the rails. Run trains. Everything work okay?

Thanks for all your help. I have removed all rolling stock from the train set and added all back on one at a time. Also in different order, with everything running successfully. It has been frustrating to say the least. Again thanks for your help. Although I am still happy with the product, installs easy, programing even easier, sounds great, and engines run great together. Still glad I made the change. Although I was wondering and still am if the PWR-56 could supply the power for O scale 2 rail.

Alan, I have some of these not installed yet. What would you recommend to use to cover the L/N/Ground?
