Ross double crossover short

Starting simple:  Do you have a multi meter where you can measure the voltage at the track?  If so, with the power bricks on, measure the AC voltage across where the track is isolated.  If it's in phase it will read near 0 volts and if not, something around 18 volts.

I don't ever seem to remember the 180 watt power bricks as having a phasing problem.  Are they both plugged into the same AC outlet?  I've found AC outlets in my house that were wired backwards.  If one outlet is correct and the other reversed, the power from the bricks will be out of phase.

I don't have any 180 watt bricks myself.  I have older 135 watt versions.  If you've covered the simple stuff, please post the information from the ID tags from your power bricks.  I am sure someone else can chime in if there is a potential one of them is wired wrong.

The are both plugged into the same powerstrip.

There were some early bricks that were wired wrong. Lionel provided plug in fixes for them. I don't recall which bricks or the way to tell from the label.

You may have swapped the polarity when you solder the jumpers to the track. Try swapping those wires first and see what you get. 

On your advice, I substituted a third 180w power brick for one of the two that I had hooked up to these circuits. It worked perfectly.  So clearly, one of the power bricks is wired incorrectly.  

I guess the best way to correct this is to get an adapter with a non-polarized plug and connect it to the backwards wired power brick.  Any other thoughts?

I'll call Lionel and see if they have any more of these adapter plugs on Monday.  Thanks all for the advice.
