Hi again,

Unfortunately Bachmann wiring diagrams are not consistent.  The Annie and Connie wiring diagrams are not color coded which means that you must manually trace the wires which can be a pain.  On other locos the wires are color coded such as the shays and some others.  For some there is no wiring diagram at all.

As for the J wire notation, I have no idea what it might might stand for.  It may just be a reference for the folks at the factory.

Bill

"J" is traditionally used by electrical engineers on a "header", normally a line of pins (but often solder holes, screw terminals), When it was a row of pins, you could put a Jumper "J" between the pins to set certain operations.

Just a tradition from electrical engineers as long as I can remember (back to the 60's)
