Does any one have a wiring diagram for the 4-position in-cab reverse unit that some 343 and 346 AF 0-8-0's were equipped with? If so, would you please post it here. Thank you.

Here is the 343 wiring, originally from the factory manual.

Thanks Rich Trains. I appreciate the follow-up and diagram. I have that diagram from the K-line AF book and the web site you mentioned. I was hoping perhaps for one with a little more detail.
Sgaugian,
I was hoping the diagram made more sense while actually looking at a 343. The only other thing I can think is to reverse engineer the wiring from a working locomotive.

I like to understand the flow as well as connection points and configuration of a wiring diagram. In doing so for this 346 I discovered some important details in terms of where fiber versus metal tabs are used in strategic places. I updated the diagram accordingly. Please see above post for updated diagram. The interesting thing with this design is that the engine chassis is "live" with connection to the rear tender truck, and the body or chassis of the reverse unit is "live" with connection to the front tender truck. Both tender trucks are insulated from the tender's chassis. However, it all works when connected correctly.
