Is this the diagram you were speaking of (late Model A with coil ign) ??? The battery and charging part of it would still be correct (unless tractor was modified??) HOWEVER as you well know since you have a Magneto instead of a coil ignition there are some minor modifications:

You do NOT obviously (as shown) come off any ignition switch and send battery voltage to the mag.

I cant say sitting here if your tractor has any sort of kill switch wire and On/Off switch up on the dash??????? Or maybe theres a small push to kill button on the mags side??? All I can say I already have DO NOT RUN A WIRE FROM AN ING SWITCH DOWN TO THE MAG TO SUPPLY BATTERY VOLTAGE TO IT.

Some Wico X Mags have a kill switch side wiring terminal on them and if its grounded out it kills the spark. On those its possible to run a wire off it to an ON/Off dash switch or key etc that grounds that wire when OFF but keeps it open (ungrounded) for ON

Maybe this gets you started???
