Ventricular fibrillation is one type of arrhythmia that can be deadly. It occurs when the heart beats with rapid, erratic electrical impulses. This causes pumping chambers in your heart (the ventricles) to quiver uselessly instead of pumping blood.
A VOLTAGE REGULATOR regulates the charging voltage that the alternator produces, keeping it between 13.5 and 14.5 volts to protect the electrical components throughout the vehicle. There is also a system to warn the driver if something is not right with the charging system.
Full Answer. To test a voltage regulator, purchase a voltage meter. Connect the positive and negative ends of the meter to the positive and negative terminals on the battery. Turn the car on and push down on the accelerator to get a reading. A voltage regulator is a mechanical part that regulates the voltage of electrical equipment in a car.
