How does the voltage regulator work?
A voltage regulator is an electronic or electromechanical system that is used as an element in the battery charging system in motor vehicles. Its task is to keep the voltage generated by the generator or alternator constant despite changes in engine speed. In practice, the voltage is not maintained at a constant level, but to a certain extent, depending mainly on the generator speed, alternator load and current-voltage characteristics of the battery. Adjustment is done by changing the excitation current of the generator. In electro-mechanical systems impulse regulation is used with three levels of excitation (full, partial, off). The electronic circuits use pulsed switching on and off of the excitation current, depending on the voltage at the generator output. In current alternator designs, the voltage regulator together with the brush holding elements forms a whole and is part of the alternator. It is important to recognize at what point the failure may occur.
Check that the voltage regulator works properly
A universal meter or voltmeter is used to control the operation of this component. They help to measure two issues: whether a current is coming from the alternator to the regulator and whether the regulator output generates the correct charging voltage. Please note that checking its operation is only possible with the motor running. In addition, although it may seem that the universal meter is a simple and inexpensive device, there are a few important points to bear in mind. The meter must be correctly set to display reliable results of the voltage control, and, in addition, when checking the regulator, it is important to set the meter to an appropriate DC value. The voltage of this element should be measured in every possible wire configuration. You can check whether its value is correct by comparing its result with the manufacturer's information contained in the service booklet of the car. When replacing the voltage regulator, make sure you have done the research on how to do it and which components can work properly with your car.
Hunting for regulators
When choosing a replacement regulator, it is worthwhile to explore the subject and approach the exchange with care. The regulator should be compatible with our car model and with the trust of customers already gained. Apart from that, it may be essential that it comes from a proven source.
