Unfortunately the voltage coming out of the cable going to the spark plug is way too high to just use a rectifier for the battery. It would require some voltage regulation to bring it down to something usable. I wanted to do the same thing but I was thinking of modifying a small transformer and placing it on the engine by the flywheel where the magnet spins and then from that charging the battery. I may be wrong but I'm guessing the old lawn tractor maybe had another cable coming out of the ignition coil that went to the rectifier or something similar?
