Electrical Guru"s, I"ve done a lot of reading on various electrical setups people have done and I think I understand... Here"s what I"m planning to do. Please, someone let me know if I"m off base somewhere since I"m adding stuff and don"t have the advantage of seeing what was there originally.
Here"s my starting point. I have a 1946 Farmall A with magneto and 12V battery turning a 6V original starter. I"m told just don"t crank too long as it will heat up too much. Works for me. Spins fast and starts great. I have a battery conditioner that I use when parked to recharge the starter battery.
I"d like some lights for evening hay rides so last year I bought some 12V headlights and wired them into a couple 6V (series for 12V) golf cart batteries in the wagon that run an existing inverter for christmas tree lights on the wagon. Works good for 2-3 hours, no problem. Now I"d like to add a charging system to the tractor and I"d like to keep the original look. I found a 6V generator 1101355 cheap at a swap meet and have had some success rebuilding it. The four position original voltage regulator is shot so, I"m thinking I"ll replace it with a 12V voltage regulator and not mess with the field coils. How much risk is there, really.. with burning the field coils? I"m running lights on a 45 degree october evening, yet also pull a float in the 4th July parade which could be a 90 degree day (yet no load on the battery). Meanwhile, I acquired an old amp box that I sandblasted and repainted and replaced the ammeter. It has a 4 position switch with field resistor, headlight resistance coil and fuse. Can I use this switch as long as it"s not broken? I noticed my original manual has the generator field running up to the field resistor on the switch. But, I"m planning to use a VR, and not a cut out. Does the switch give some feedback to the generator field saying, "hey the lights are on, give me more juice." or "back off and produce less power (less heat) when the lights are off". Is that what the voltage regulator does automatically? Should I get the modern 3-position 12V switch? I don"t yet have a rear light, but am curious when that would come on. Red and white.
I forgot to mention the generator has a third brush and I"m planning to set it nearest the closest brush (two commutator bars away) for most current. Is this a bad idea since I"m pushing it by regulating up at 12V rather than 6V? I figure I could always send in the generator to have the field coils replaced for 12V if they went bad. Does the armature need to be rewound too? Gosh, maybe I should just get an alternator or take it back to 6V pos ground.

Today's Featured Article - Choosin, Mounting and Using a Bush Hog Type Mower - by Francis Robinson. Looking around at my new neighbors, most of whom are city raised and have recently acquired their first mini-farms of five to fifteen acres and also from reading questions ask at various discussion sites on the web it is frighteningly apparent that a great many guys (and a few gals) are learning by trial and error and mostly error how to use a very dangerous piece of farm equipment. It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
