How to connect a tractor voltage regulator

A voltage regulator draws current from a battery with oscillating voltage and outputs constant voltage. Six-volt generators and 12-volt alternators require current at voltages. Voltage fluctuation can damage these electrical mechanisms. A tractor’s regulator takes the voltage provided by the battery, manages it by lowering it, and sends it to the alternator or generator at a constant volume that the alternator sends to the coil. There are three wires that must be connected to the correct regulator terminal.

Step 1

Weld the governor bracket to the tractor frame. Weld the bracket between the alternator or generator and the coil housing. Follow the mounting instructions in the regulator manual for correct bracket positioning. Some recommend vertical mounting while others require horizontal positioning.

Step 2

Attach the regulator to the bracket. Screw or screw the four corners of the regulator to the bracket. Typically this requires four screws or bolts and four washers and nuts. Do not overtighten the bolts or you will damage the regulator housing, especially if the housing is made of plastic.

Step 3

Connect the positive battery cable, usually red, to the regulator. Connect the wire to the terminal marked “B” (sometimes this terminal is marked “BATT”). Connect the alternator or generator cable to the regulator. The corresponding terminal for the alternator / generator cable is marked with an “A” or “G” (sometimes “ARM” or “GEN”). Connect the field wire – field coil wire – to the field terminal on the regulator. An “F” or “FIE” indicates the field terminal.

Bias the generator or alternator through the regulator. Touch one end of the jumper wire to the battery terminal on the regulator. Touch the other end of the wire to the field terminal. Hold it in the terminal for one second and then remove it. You will damage the regulator if you hold the jumper wire to the battery and field terminals for more than one second.
