I was confused in my answer. I made a jump to the conclusion that you had a 4 position light switch. The low charge operation of a voltage regulator is produced from two interconnected elements. The first is that the voltage control points on the voltage relay (not the cutout relay) vibrate into contact and out of contact as the voltage setting is reached. It does not go to a condition of "Low charge" it tapers to less and less charge as the battery fills. The voltage remains at 7.2 or so and the amps go down proportional to the state of charge in the battery with constant voltage. Easy to fill lots of amps when the battery is low, and more difficult to fill when near full. The secong element is a wire wound resistor (usually under the base to allow heat dissipation) that causes a continuation of charge rate even if the contacts in the voltage relay were open, and while they are open as they vibrate. The cutout is responsible for connecting the gen to the battery when the gen puts out enough to charge the battery, and disconnects it automatically when the gen does not meet this requirement, As when shut off. If it does not disconnect the gen, battery current will back flow into it and let the battery drain, and the gen to overheat. Connections: Find attached the diagrams! The gen F terminal is attached to the Reg Field terminal (12 gauge wire no other connections) The Gen terminal (could say Arm) on the gen connects to the Arm terminal on the Reg with 10 gauge wire (no other connections). The Bat connection on the Reg connects to the Amp gauge load side (the side not connected to the Starter switch.) If it has a L terminal it connects to the Light switch fuse supply terminal. Jim

Today's Featured Article - Pitfalls of Tractor Engine Rebuilds - by Chris Pratt. The first pop after you have put the machine together with your own hands is exciting and pleasing. The whole experience can be marred if one moves too fast and makes too many assumptions that they can just use "as is" some parts they should be closely scrutinizing and possibly attended to. In such cases, rework makes what could have been a fun project turn into an irritant or even a nightmare. Minor Irritants To give you an example of an minor but irritating proble
