Prewar AF wiring (4-4-2)

[RobsLocomotiveBackshop]

 Hi all,

 

I'm in the midst of a repair job for a friend and it's turning out to be a ressurection more than a repair.  Someone has really screwed up the wiring and I'd like to know what goes where and why.  I can't find an AF specific diagram on the web as of yet.  Any help would be appreciated!  Can PM or email if you wish.  ([e-mail])

 

Thanks!

Rob
