DR-13B Checking A/C Cutout Relay Control Circuit

1. Turn ignition switch Off, then connect a voltmeter to terminal No. 3 of logic module blue connector and to ground.
2. Turn ignition switch to Run position.
3. If voltmeter is indicating voltage is within 1 volt of battery voltage, replace logic module.
CAUTION: Before replacing the logic module make sure the terminal in cavity No. 3 is not crushed so that it cannot touch the logic module pin.
