Clearing up mud (letting it settle) The internals of the switch have two seperate parts, one is for charge control, the other is lights. They are on the same shaft, and in the same Molded plastic housing, but do not connect electrically. The light sw part has a D and B function which takes its supply from a wire going to the Amp meter load side. The D position connects this power to a resistor (on the switch), then to the light wire out put. The B position connects the same input to the light wire directly, no resistor.
(I would have put two bulbs or filiments in the bulbs and had the D control one, and the B control the other, much brighter than normal lamp, but I was not born then nor working for IH)
The Field control is (for sure) not connected to the power at all. It is "ground only" (through the switch internal bushing and mount to the Electrical box). This is direct to groung all the time when the H D and B positions of the Switch knob are selected. When in the L position (full CCW), the Field is grounded through a wire wound resistor (also mounted on the Switch). This resistor cuts the field current to about 13 of full output. #4 on bobs diagrams. (If I remember) JimN

Today's Featured Article - Tractor Traction - by Chris Pratt. Our first bout with traction problems came when cultivatin with our Massey-Harris Pony. Up till then, this tractor had been running a corn grinder and pulling a trailer. It had new unfilled rear tires and no wheel weights. The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc
