Allis chalmers HB112 wiring help

[deans]

I have been given a HB112 lawn tractor, partially apart with a 12 hp briggs and Stratton engine. motor actually runs good. It has a starter generator, regulator, and solenoid but no wiring, it was taken off before I received it. I have a new 5 tab ignition switch with B,A,R,S,and I marked on back side. Does anyone have any info as to rewiring this tractor, any and all help would be greatly appreciated. deans

b=battery, a=accessory, s=starter I= ignition not sure about "r". The regulator will have letter marks as will the starter/gen. The briggs engine will have a "kill" wire that is grounded to shut down the engine. It will have a built in mag so does not need power to run. If you can find a wiring diagram from any tractor using a briggs or kohler and a starter/generator it will be the same or close. Cub cadet comes to mind and might be easier to find a diagram for.
