Bill gave an excellent discription of the operation of the cutout system. If your question is directed for troubleshooting, I will add my 2-cents.
The cutout is a relay. After the tractor starts, the contacts close and connect the generator to the battery. When the tractor is shut off, it opens. Obviously if it doesn't close, it won't charge and if it sticks closed it will discharge the battery.
The light switch controls the charge rate by controlling the generator field current. Grounding the field windings will produce maximum charge. This is why Bill mentioned the importance of grounding the instrument box. The light switch connects the generator field windings through a resistor to ground for "L" charge and directly to ground for "H" charge.

A voltage regulator has a set of "cutout" contacts and a second set of contacts to automatically control the generator field current (charge rate).
