(3) Closing voltage. To check the closing voltage of the cutout relay, the voltage regulator must be connected
with the generator and battery. Connect a voltmeter between the regulator GEN terminal and the regulator
base (16). Slowly increase the generator speed and note the relay closing voltage. The correct closing
voltage is 12.0 to 15.0 volts. Decrease the generator speed and make sure that the circuit breaker contact
points open. Adjust the closing voltage to 13.5 volts by turning the adjusting screw (7). Turn the screw (7)
clockwise to increase the spring tension and closing voltage-counterclockwise to decrease the closing
voltage. The closing voltage checking is shown in figure 113.
