Relay Unit Closing

1. Connect battery lead "B" of tester to 1-1/2 ohm connection on side of tester.

2. Turn field control variable resistor to "Open" position.

3. Turn load control knob to "Direct" position.

4. Operate engine at approximately 2000 RPM (35 MPH).

5. Slowly turn field control knob toward the "Direct" position to decrease resistance in generator field circuit. As the resistance is decreased, voltmeter reading will increase until a kickback of the voltmeter needle is observed. The highest voltage noted will be the cutout relay closing voltage. Repeat operation several times, each time turning the field control to "Open" position. If the closing voltage is not within specifications (see Fig. 51-1), adjust according to manufacturer's Service Bulletin and retest.
