These regulators are often mounted inside the alternator or on the outside of the alternator end frame. Electronic regulators are nonadjustable. Some older vehicles have electronic regulators mounted externally from the alternator. DaimlerChrysler vehicles manufactured since 1 985 have the voltage regulator designed into the PCM.

The unit consists of a cutout relay, a voltage regulator and a current regulator, all of them mounted on the same base and enclosed by the same cover. The voltage regulator or the current regulator may be operating at any one time but in no case will both of them be operating at the same time. When the electric load demands are high Figure 191.

CIRCUIT BREAKER GENERATOR — RA PD 368820 (3) This method of generator regulation is termed current regulation, since the current output of the generator is used for regulation. It is, therefore, very important that no breaks occur in the charging circuit after the generator reaches a voltage sufficient to operate the circuit breaker. If a break does occur, no current will flow through Because it has no moving parts, this solidstate voltage regulator is capable of switching on and off about 7, 000 times per second Old mechanical voltage regulators were only able to do this for about 200 times per second and required periodic adjustments and eventually wore out Courtesy.of CARQUEST Auto Parts controlled. Figure 54 displays how a vibrating contact point regulator controls an alternator's field coil strength. A voltage regulator controls the amount of time an As a result, the generator will never produce more than the predetermined rate (for example, 40 amperes), no matter how high the speed of the car. This will be true regardless of the Voltage Regulation. (1) A circuit diagram of a typical vibrating voltage regulator is shown in figure 1311. Although the construction of this relay does not differ materially from that of the current regulator, the principle of operation is somewhat different. With this regulator, the voltage output of the generator This is a complete reference guide.to automotive electrics and electronics.Then, when the alternator FIELD OR ROTOR TERMINAL JUMPER OUTPUT ALTERNATOR / TERMINAL Figure 4 When the boat's storage battery is dead, the alternator can be tickled into operation by exciting the rotor with a dry battery, as shown. A lantern battery or several flashlight cells in Series will do it. starts putting out, the regular battery can take over. Regulation The conventional generator control box has a reversecurrent cutout, voltage regulator and current limiter. But most Such a circuit finds wide use in many electronic applications and forms an essential part of an automotive voltage regulator. Obviously, the simple circuit just described could not be used directly to regulate a charging.system. But Fig. 317 shows how it might be incorporated into a regulator that can control the voltage in an actual system. Although circuit details differ among the various makes, practically all solidstate voltage regulators operate in a manner equivalent to the one we are
