[quote:09fe9d4c95]A cutout relay lets current flow from the generator to the battery but prevents it from going the other way, so you can charge the battery up but it won't just drain back down through the generator. The tractor operator controls the charging rate with the light switch, which has four positions: High, Low, Dim, and Bright. If the lights are on (Dim or Bright), the generator charges the battery at the high rate. If the lights are off, the generator charges at either the high or low rate depending on the switch position. Too little charging and the battery will run down; too much and the battery can be damaged. An automatic voltage regulator has the same basic job as the cutout relay, letting current flow from the battery to the generator but not the other way around, but it also solves the under- or over-charging problem. It lets current flow from the generator to the battery whenever the battery voltage is lower than it ought to be, but then stops as soon as the battery is charged back up.
With a regulator there's no need for the operator to manually control the charging rate, so the wiring between the switch and the regulator is a little different than it would be for a cutout relay. And there's no need for the High and Low positions on the light switch. (On tractors that came equipped from the factory with a voltage regulator, the switch was truly just a light switch, and had only three positions: Off, Dim, and Bright).[/quote:09fe9d4c95]
