John, great post! However you need to add that the wire from the field post on the Cutout box may not connect to the field post on the genny. On some early cutout boxes there are only two posts ARM and BAT. If so the field of the genny goes to the resistor at the light switch. The switch sets the charge rate low through the resistor and grounds the field wire for high charge. Later cutout boxes have 3 posts with a built in resistor from the field post to ground. If the genny field is connected to both the switch and the cutout FLD post the charge rate would be higher in the low charge position of the switch because the two resistors are in parallel. The IH book says to remove the wire from the Cutout box field post to the genny field post if the tractor is to be used for extended periods without lights, presumably to help prevent over charge.
