431/441 electrical schematic

I have a tractor that was originally built as a 431 but was repowered with a gas engine. So I guess you would call it a 431 now. It turns over nicely but I'm not getting any spark. It is set up for positive ground. I have read about A circuit and B circuit units and am not sure how to know which I have. Does anyone have schematics of both versions? I have the I&T shop manual but all it has is a wiring diagram that doesn't have enough detail to show what wire goes on which terminal.
 
Luke, just sent you the diagram from the Case Parts site on line. This should help. If not let me know maybe I can scan the pages from my 630 Case Service manual. Should be close to the same on a gasser.
