The generator produces the necessary electrical power for the various power consumers (ignition, lights, engine preheat, turn signals, horn, etc.).
It is also used for charging the battery power supply that is essential at the start

The generator voltage is lower than the battery control lamp lights up.
Second.
Second.
The alternator voltage is higher than the battery, the battery is charged. The control lamp is shorted and thus extinguished.
Engine and generally always be able to supply sufficient energy, if the alternator is not enough revolutions or stopped.
During loading, the same poles of the alternator and the battery is connected, as shown in Figure 66.
Now the alternator charge the battery only then, when the alternator voltage is higher "than that of the battery. Therefore, no fixed connection as used in FIG 66, because then, when the generator is running slowly or stops, the battery is discharged by the alternator. It is therefore a switch between battery and alternator installed that connects both, while the generator has enough power.
This is achieved by applying an automatic switch at the right times the generator on and off.
The automatic switch is usually placed on the alternator). The interior of the solenoid operating switch is seen in Fig
On a metal base plate is a vertically mounted iron core. Nearby above the core lies a spring anchor, in which a tungsten contact pin is riveted. The fixed contact is insulated from the base and the positive terminal of the battery connected. Through these contacts, the connection is enabled or broken alternator battery.
The normal schedule of an automatic switch in Figure 67 and 68 drawn.
is a tension coil, consisting of many turns of thin wire, the coil 2 with few turns of thick wire, the resilient anchor 3 and 4, the charge indicator light.
The diagram shows the current flow but not enough voltage to the battery gives'ning-tion can load, so the contacts are opened.
Enable. When we spin the alternator faster, (by giving the engine more gas), increases the generator voltage and current, the voltage in a coil to the iron core is more energized.
When the generator voltage V ± Yi higher than the battery voltage, voltage energizes the coil the iron core filled sufficient to pull the anchor to do, the voltage at which the contact closes, called circuit voltage. The dynamo-battery connection is established. The revolutions of the alternator is ± 600/min. The current course is according to .
The voltage coil remains energized, but the main passes through the coil to the battery. Thus, the core of the electromagnet even more energized and resilient anchor drawn with greater power, the contacts are thus more firmly pressed together (they can while driving through the vibration of the car is not open!).
Off. The number of revolutions of the alternator off, it also decreases the tension. If the alternator voltage equals the battery voltage, then there is no current through the coil (still through the coil tension!). Voltage drops more than vioeit a current of the battery by the alternator. Because the discharge in the opposite direction through the coil is, does this ratification of the coil voltage against which the resilient anchor jumps back and the contacts open. The compound dynamo battery has been disconnected.
Monitoring the working of the automatic switch. Systems with three brush dynamos are usually equipped with an ammeter. Through this ammeter we can verify that the automatic switch at the right time on or off. Is the power voltage is correct, then gradually accelerate from the current start charging some amps. The ammeter indicates a high charge current of a sudden, this is due to a high voltage circuit. • When the ammeter shows a discharge on power, this is the result of early activation of the automatic switch. The circuit voltage is then too low. The ammeter gives us an opportunity to determine whether switching off takes place at the right time. This must be a you-Schied ontlaadstroomsterkte from 2 to 4 amp (back flow or return flow).
