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.
Controls on the driver's side of the footplate. The regulator is the 'throttle' of the locomotive; it controls the delivery of steam from the boiler into the cylinders. With the regulator fully open, a high volume of steam is admitted, and maximum power may be generated. However, the cylinder power is influenced by the reversing gear.
