DC Wiring Problem

OK, so I’m a newbie. I am having a wiring problem which I’m sure someone more experienced has solved in their sleep. I have all my turnouts facing the same way save one. I put insulated rail joiners between that one and the main line. When I connected my feeders, the train runs on each (three feeder lines), but when I connect them all together, I get what must be a dead short (nothing moves anywhere). What did I do wrong? Thanks!!

It’s really hard to solve electrical problems without seeing a diagram. A diagram of your track, where you have your feeders connected, and where you have your gaps. Sooo… you will need to learn how to draw and post pictures here first. Sorry.

Someone else may try and take on your problem without them, but I can’t.

I’ll wait till i’m sleeping and answer you then !..

What kind of turnouts, is this on a straight track or in a loop, is there a ladder involved, which one is not the “same way” is it one of the ones on one of the ends or is it one in the middle, where are the power feeds currently, are you using common rail wiring, etc. etc.

Which one? The one going the other direction? Why did you do this?

Do you mean there are three parallel tracks and each has its own feeder pair? When you connect each of the feeder pairs alone and individually everything works fine?

Do you always connect them all together. Why not connect one, get it running, connect the next, etc. until you isolate the ONE causing the problem?

Sounds like a simple polarity problem.
