If the cables that connect the alternator, voltage regulator, and battery are damaged, then they will not transmit power as they should, resulting in a low battery. Replacing a faulty voltage regulator will you anywhere between $330 and $450. ![]() As a result, the voltage will start dropping and if it reaches a point where the battery does not get sufficient charge, the sensor will take note and alert you by blinking the car battery on the dashboard. ![]() When the voltage regulator is damaged, it will not be able to control voltage.
