I picked up a DCC Equipped FT-A from the hobby shop, I put it on my track, turn on my Zephyr, and it shorts out. Repeatedly. I don't have a working DC power pack on hand to see if it works on that, but I'm guessing it won't. I popped the shell off and didn't see anything obviously wrong, except that the rear pickup wire colors are reversed. The connections are correct, but the black and red wires are on the wrong sides.

I'm completely new to the hobby and don't really know my way around the inside of a loco very well. The hobby shop sold it to me as new but deeply discounted due to missing packaging and documentation. I don't have a registration card to enforce the Bachmann warranty. The hobby shop is willing to take it back for a full refund, but I'm hoping to find a solution that doesn't involve another 75 mile (one way) drive up there to end up without a DCC loco.
