after waiting 6 years, I was finally able to find a WBB Alco FA AA set for Lehigh & New England at blowout prices. I placed the power A unit on the track and nothing. no forward or reverse, bell, horn, and lights worked. took the shell off and turned off the lights and saw the blue sparks. found the black wire on the rear power truck had rubbed the plastic coating off and was shorting on the frame.
now this was new in the box, still had the plastic wrap on it. taking it to the ups store to ship it to bachmann today, they told me 4-6 weeks turn around time. 4-6 weeks seems kind of long for a simple repair of a wire and possibly a new reverse board.
