I guess I am biased once in a while.  I think that doing DCC without a multimeter is like walking in the dark in the woods at night with no moon.  If it beeps, even softly, tells me when the wire is connected, tells me that I’ve got power, tells me how many ohms an unreadable resistor is, or checks to see if I’ve burned out an LED, then I could be happy.  If it costs one tenth of what mine cost maybe it could make someone else happy too.

I have a few of these marvelous Allegheny locomotives, and recently decided to sell one of them. The buyer ask if I could test run one of them he was interested in. Since I just got my lower deck up and running, I thought why not run this test on a few of my Alleghenys, included a really heavily weather one I bought years ago and don't recall if i ever tested it.

Thanks to the very informative description provided here by Prof (thanks Prof!!!), I thought I understood how to power my frogs using the Walthers switch machine.

Alas, I am doing something very wrong because the frog's power source is not changing to match the routing of the switch. 

A little background...

-I am using HO scale Fast Tracks turnouts that I have built and tested.

Track laying,..electrical question

I'm a little confused with this observation of mine. I've been laying lots of code 100 atlas track lately,...and attaching the multiple feeders wires to the bus wires. The area I have in question is down one side of the layout under my steel mill and freight yard tracks.  Its all going to be a single power district with a single bus wire feeding it.

That single bus wire stretches the length of side of the layout and has open ends (no connections at this time on either end).
