First, welcome to WFM, Matt!
Since I have no idea what the old Kohler Solid State Ignition or magneto ignition looks like, I should probably not be posting. However, if it's possible that the one wire coil is something of that nature, and it saves Matt from more problems, I don't mind showing my ignorance.
Having only one wire on a coil and getting some pulsing voltage is difficult to understand from a conventional old style automotive coil. Perhaps you can give us more info such as the serial number on the tractor or the spec. number on the engine. Is it a 12HP (K301) or 14HP (K321) engine? Does the engine have breaker points?
Could you post any pictures or e-mail them to Roger, me, or another member to post for you. Might be something interesting to see.
JD Parts is not available for me at the moment. Maybe I can take a look later.
