Hi, I saw your website and thought to take a shot at asking a question I need answered.
This concerns old Delco-Remy tractor generators without ventilation (closed case).
Questions are:
First, how can one tell if you are looking at a 6 or a 12 volt generator if you have it apart?
I am trying to convert an ancient Allis Chalmers B tractor (1940 model, positive ground, magneto ignition) from a 6 volt to a 12 volt system without having to use an alternator but rather a 12 volt generator to maintain appearance. With this said, what I have now is a functioning 6 volt Delco system with a voltage regulator fitted to the generator instead of the original cutout and high/low range switch (switch was burned when I got the tractor).
I have another generator given to me which is supposed to be 12V (from a Case) but after cleanup had a rebuilders' tag indicating that it's 6V. This generator (of course) has no manufacturer's number plate so I am stuck.
Now, I have both units disassembled. I note that the field coils' center plates on the "12V" unit are a bit larger than the 6V unit I removed from the tractor. I also note that the "12V" unit's armature rotor windings seem to be in a different direction than on the 6 V unit.
How do I know if it's a 6V or 12V unit that I got given?
Second question is: Does direction of rotation make a difference when dealing with generators?
thanks for any advice or enlightenment... The 6V system I currently have is just not up to the cranking task which is why I want to replace it. I do have the heavy duty 6V cable and ground strap installed and a fairly new battery. I have to jump start the tractor almost anytime for a hot start which is really aggravating.

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
