Up to about 1949 or 1950, on the H you could get two types of lighting systems. One was the "no battery" Bosch system, and the other was the Delco-Remy system. The Delco system used a generator, battery, the associated wiring, and two front lights with one rear.
Some time in '50, the H used the newer Delco system, but this one had full voltage and current regulation. The older system had a voltage cut-out and a third brush in the generator. The easiest way to tell the difference between the two systems, was by the light switch and the regulator. In the later system, the regulator was located on the rear fuel tank support, directly behind the steering post, and the light switch only had three positions.
The older Delco system had the "regulator" (this was the cut-out) mounted on the top of the generator. Both the old cut-out, and the newer regulator looked the same, but were electrically different. The switch on the older system had four positions as follows from extreme counter-clockwise to extreme clockwise: L(ow), H(igh), D(im), and B(right). A previous poster outlined those functions.
To double check the system you have, and verify the type, just look at the generator part number and check that with the parts book. If your tractor is a '48 or earlier, it is a pretty safe bet you have the older system.
A disclaimer here on identification: I have heard that a few of the early regulated systems had the regulator installed on the top of the generator as was done in the old system. In such a case, you definitely need to check the part number on the gen. to verify the type.
As a short cut, you can also remove the band on the back of the gen. and simply count the brushes inside. The new generators only had two brushes, while the older ones had three.

Today's Featured Article - Product Review: Electronic Ignition - by Staff. Oil, for example has come a long way in the last 50 years and I don't use anything but the latest API grade available. I've heard the arguments for non-detergent oils but would never trade it for today's formulations. Paint is another, the modern acrylic enamels are great for resistance to grease and fuel stains, retaining their shine and they last forever; unlike enamels and lacquers . Still another is the alternator. No doubt using the original generator keeps the tractor pure, but for thos
