The voltage regulator despite its compact size, is one of the most important elements of electrical equipment. This essential operation unit must be in good condition.
Principle of operation and purpose of voltage regulators
The voltage regulator controls an alternator of a car, keeping the output voltage within normative range. Thus, the maximum permissible voltage on the battery and on-board network of the car is not exceeded.
The voltage regulator is necessary in order to stabilize the voltage in the device. When the car’s engine is running, the voltage in the car’s electrical system must be at the same level. But the crankshaft rotates at different speeds and the engine speed is not the same, as a result, the alternator unit supplies different voltages. It is necessary to adjust this parameter to prevent malfunctions in the operation of electrical equipment.

Signs of voltage regulator breakage
The voltage regulator may have a different look:
- voltage regulator in the form of a module of the brush assembly, uses its design as a carrier base;
- Separate element mounted on the housing of the support bracket.
The voltage regulator, in any form, is a non-separable element. If this component breaks, it can’t be repaired anymore.
If the voltage regulator breaks down, the failure of this element is accompanied by undercharging or recharging the battery.
Shortness of charge causes the following problems:
- car engine does not start well;
- starter cannot rotate the crankshaft;
- car is completely de-energized.
The consequence of recharging the battery is boiling electrolyte. It is easy to detect this problem: the terminals and the case are covered with a characteristic white coating.
With the appearance of the above signs, it is necessary to conduct a comprehensive diagnosis of circuits and alternator circuits.
Diagnostic process of the voltage regulator is performed using special devices. Practice shows that such a check requires minimal preparation of a master. Diagnostics are carried out according to the general scheme, and on cars of different brands the diagnostic process differs in some details. Diagnostic is carried out with voltage regulators and other alternator circuits to make test result more complete and accurate
Professional equipment
Professional equipment of MSG Equipment is convenient, easy to use, installed in specialized services stations. Its use in work provides fast and accurate diagnostics. Thanks to the advanced experience and know-how benches and testers of MSG Equipment are in demand on the domestic and foreign markets. The export geography of MSG Equipment includes the CIS countries and the EU.
The tester MS012 COM checks automotive voltage regulators with a voltage of 12V and 24V. The test is carried out under different loads. The MS012 COM tester is useful for testing voltage regulators with various connection terminals.
The use of the tester is always relevant, as for updating data, a USB connector is provided in its design. The tester is distinguished by its compact size, modern design, and the accuracy of the measured parameters. The device is equipped with built-in short circuit protection, that prevents its breakdown if the voltage regulator is connected incorrectly.
The MS013 COM tester tests the operation of a voltage regulator with a voltage of 12 V. The device performs diagnostics in two ways:
- testing the voltage regulator assembly with the alternator (on car or bench);
- diagnostics of the voltage regulator taken from the alternator.
Using this tester, you can check any voltage regulators.
MSG Equipment offers equipment for large service stations and small workshops. Modern, multifunctional benches and testers are advanced diagnostic devices. The use of MSG Equipment devices makes easier and speeds up the work of personnel at service stations.
