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.
The voltage regulator has two functions. 1) Regulate the voltage to the battery so it doesnât exceed 14 volts (actually 14.2 volts). 2) Disconnect the battery from the generator when the voltage from the generator gets too low as when the generator is turning slowly or stopped.
