(3) You should now review the regulator testing procedures in lesson 4.
6. SUMMARY. In this lesson we studied the purpose, operation, and testing of
regulators. The need for regulators was brought about by the instability of the
generator output voltage.
a. To protect the battery and accessories is the big job of the regulator.
It does it by controlling the generator.
b. The regulator does its controlling by varying the field current of the
generator. This field current is turned ON and OFF at particular rates, thereby
efficiently adjusting the output voltage.
c. The relay type, carbon pile, and action of the solid-state regulators
were discussed. It was found that most every regulator has a line switch relay to
remove the load from the battery.
d. Tests are performed on the line switch relay and the function of
regulation under load conditions.
