Tester for diagnostics of voltage regulators. The device simulates control signals for a tested voltage regulator. It contains integrated physical and program interfaces of all actually existing control modes of modern alternators. Adapter is controlled by clock encoder with button to install and change parameters. Installation and parameter data appear on LCD display. The tester possesses the opportunity to change existing and implement new functions and interfaces in the software. Update download is carried out through USB port. Built-in power supply gives an opportunity to use the device as high-precision ohmmeter or generation of arbitrary PWM signals. Diagnostics lasts about 2 minutes.

Alternators of modern cars are equipped with semiconductor electronic voltage regulators. Regardless of the manufacturer, the operating principle of the voltage regulator remains unchanged: the regulation of the field winding current, depending on the rotor speed, with the voltage stabilization at the alternator output.
In order to check the correct operation of the voltage regulator, it is necessary to set the required voltage at the input of the regulator and check whether the regulator provides maintenance of the specified voltage at the alternator output.
The check of the voltage regulator on the car is carried out in the following sequence:
connect the voltage regulator tester to the vehicle electrical equipment;
start the engine of the car and wait for its stable operation at idle speed;
check the voltage values on the display. If the voltage is below the rated voltage, check the belt tension of the alternator;
change the value of the voltage on the alternator (if the model of the voltage regulator allows it) - the voltage on the adapter must change in accordance with the preset. Otherwise, check the voltage regulator separately from the alternator.
The most common cause of such cases is the wrong connection of the device being tested. Therefore, before searching for a solution, we recommend you to check the correctness of the connection with the instruction manual attached to the stand / device. A further option is to update the firmware, which you can download from our website. In any case, you can contact us in one of these ways, we will test the identical relay-regulator in the conditions of our laboratories, and let you know the result.
