Okay, I am new here so please be kind if I am asking a really dumb question....

To start off I have other Bachmann DCC locos that work fine on my setup...
I recently purchase a BLI DCC equiped loco and it won't run on my DCC setup, it is signaling a short (the lights on the controller are blinking fast)... I changed out my DCC controller and put in an older DC controller and the loco works fine.

Any thoughts or comments would be greatly appreciated.
