CAUTION: Remove power from unit before making the resistance measurementNOTE: The resistance measurement between the com and VS voltage pads should read approximately 3M ohms with voltmeter leads oriented as shown in the diagram. If the voltmeter leads are reverse the reading will be infinite.A typical faulty reading is 500 ohms. Replace the YDT or YDB if a low resistance is measured.
