Agricultural Rectifier & Regulators does the same thing a regular rectifier does: It converts alternating current to direct current.

The reason you need Agricultural Rectifier & Regulators is that the Agricultural tractor equipped with an alternator, which is just a device that takes power (in the form of rotation) from the engine and converts it into alternating current (AC). Think of the alternator as a type of generator.

Now AC is a fine source of power for lights, but you can’t feed AC into a battery or into a fuel injection computer and expect it to work.

The Agricultural Rectifier & Regulators job is to convert this AC power into Direct Current power so it can be used to charge the Agricultural Tractor battery and otherwise power all the 12 volt (DC) devices on your Agricultural Tractor (electronics, tachometer, etc.) we sale new replacement regulator/rectifier units for farm tractors and agricultural equipment. for Case, Bosch, Ford, International, New Holland, Allis and more.

It’s worth mentioning that generally a rectifier is combined with a voltage regulator, which makes sure the alternator doesn’t generate too much (or too little) power/voltage.

If your alternator were to generate too much voltage it would overcharging the battery, burning out your Agricultural Tractor electronics, etc. And if it generated too little your battery would slowly drain (this is the most common failure in a Agricultural Rectifier & Regulators)
