I was asked to give a 24 volt Seminar at a couple of the JD shows I attend but resisted it big time, they finally talked Tom into giving it and I attened but most attendees had that deer in the headlights look lol. One problem is the old wires are faded so theres no longer much use in trying to use a color coded diagram. Also theres so many wires crammed under the dash around that switch its just tough (even if you knew what you were doing) to trace and troubleshoot things.
Seems some semi trucks used a series/paralell switch relay system so they could put 24 volts to the starter and then all was back to 12 volts. Years ago I used to buy combination 6/12 volt batteries with a series paralell relay in the middle so the vehicles started on 12 then ran on 6 volts. EITHER of those may be easier to understand then Deeres 24/12
Fun discussion but likely not much help to many here.
