The car voltage regulator consists of two parts - the "voltage regulator" (the left coil) and the "cut-out" (the right coil).
Lets deal with the cut-out first. This acts like a switch which operates at a given dynamo output voltage. When it switches in, as the dynamo speed increases, it connects the car battery to the dynamo via the regulator, and hence charging can commence. When the output voltage is too low (at low dynamo speeds) the cut-out drops out to prevent the battery trying to run the dynamo like a motor, which would quickly drain the battery. From this you can see that the cut-out is of no use to us if we are just using the dynamo to run some lights from our stationary engine. I've included it's explanation for interest, as it's an integral part of the whole regulator box.
The National Highway and Safety Administration issued loose guidelines for driverless car regulation last month, urging states and cities to coordinate new rules so a mishmash of regulations doesn't impede the development of driverless cars. The federal government believes the technology will dramatically reduce traffic crashes and deaths.
The car window regulator in your vehicle is the component system that controls the raising and lowering of the side windows in your car. There are two primary types of window regulators; automatic window regulators use an electrical mechanism to raise and lower the windows in the vehicle according to a switch that you flip. Mechanical window regulators have a detailed system of gears and interlocking parts that require the passenger or driver of the vehicle to turn a small knob on the inside of the car door in order to raise or lower the window. The cost of fixing a broken window regulator on your car is dependent upon a number of different factors, the most important of which is typically whether the window regulator system is automatic or mechanical.
Any vehicle with an alternator needs a car regulator to prevent the voltage moving through the system exceeding safety levels. The car regulator is in essence a voltage regulator that allows enough voltage to charge the battery but not so much as to blow out circuits or lights.
