DCC WIRING.

[Newfiegod780]

Need some Bachmann DCC wiring help. I have 5 powered rerailers throughout my layout,  my plan was to attach my control board to the first rerailer on one side and then go from the other side of the rerailer to the next one and so on. When I first hook up my main feed it is fine but when I connect the next rerailer the Bachmann controller blinks fast indicating something is not right. Any help would be appreciated. I assumed the out side of the rerailer was to carry power elsewhere, is that incorrect?

You probably have the polarity wrong at the second rerailer. Try flipping the plug over and reconnecting it.

I got it figured out, changing the wires around didn't change anything but when I flipped the connector over it worked perfectly. Checked voltage all around the layout and it was consistent all around. Thank you for the help!!
