The serial number listings are too the left on this site (classic view, not Modern view) the voltage and polarity are originally 6 v and positive ground. but that is an assumption because farmers change things very often. A mag ignition will have a built in coil on top with a kill switch that grounds the mag to kill the engine. Mags do not have any connection to voltage from the electrical system. One wire goes to the kill switch and the switch body grounds that wire to stop spark. A distributor system will have a cylindrical can type coil separate from the distributor body and the ignition switch will have one wire to the coil, and one to a voltage source. Good luck. This site sells manuals and parts. Jim
