An alternator voltage regulator is essential for sustaining the right voltage output of an alternator, which is answerable for charging the battery and powering electrical elements in a car. A defective voltage regulator can result in overcharging or undercharging of the battery, which may trigger injury to the battery and different electrical elements.
Checking the alternator voltage regulator is a comparatively easy process that may be finished with a couple of primary instruments. First, disconnect the adverse terminal of the battery. Then, use a multimeter to measure the voltage between the constructive terminal of the battery and the output terminal of the alternator. The voltage ought to be between 13.5 and 14.5 volts. If the voltage is beneath or above this vary, the voltage regulator could also be defective and must be changed.
