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 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.
