Howdy folks, new to the forum here so pardon me if Im overstepping any edict or rules.
My question for you folks today is along the lines of the electrical components of the Nuffield Universal 3 tractor.
Ours in a nutshell, has none. and while she starts like a charm and seems to run pretty well, after 14 years in the previous owners hands having never gone through so much as an oil change, I fear were merely hopping on and crossing our fingers everytime we try to start her up, and im lookin to change that.
Im a Carpenter by trade, and am fairly new to the world of tractors, electrical & engine repair entirely, although I did manage to fix our snowblower rolleyes , so I wouldnt say im a complete nub around tools and machinery, and im a pretty quick learner if I say so myself wink
None the less, Im currently in the process of starting off slow and working solely on getting the lights up and running. Now as ive mentioned, our tractor is pretty bare bones, and while looking through the manuals wiring diagram a few times Ive come to the conclusion that we have no 'control box' or alternator regulator as, if im correct, it is modernly called. nothin behind the guage panel, where its supposed to be, cept some worn out wires. The starter solenoid hooks directly to the battery as does the alternator, both being on the same terminal.
now from my own research, it seems some of the newer alternators have the regulator attached already, and while ours definitely isnt the original dynamo nuffield slapped on there, it certianly isnt the newest looking piece of equipment, still gotta check the dates, but say it is one of them newfangled ones, how would one go about wiring in a control box? or would one even need to?
I guess what im tryin to say here is that were lacking a control box, and from what ive read, it seems like its somewhat of an important piece, but assuming that the alternator we have on now has one attached, would there be a need for installing a seperate one? or would we just have to wire everything through the existing one.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
