Precautions: Voltage check If voltage is supplied to the circuit being checked, voltage check can be used as circuit check1) With all connectorscouplers connected and voltage applied to the circuit being checked, measure voltage between each terminal and body ground2) If measurements were taken as shown in the figure and results were listed in the following, it means that the circuit is open between terminals "A" and "B"Voltage between "A" and body ground: Approx5 "B" and body ground: Approx5 "C" and body ground: 3) Also, if measured values are as listed following, resistance (abnormality) exists which causes the voltage drop in the circuit between terminals "A" and "B"Voltage between "A" and body ground: Approx5 "B" and body ground: Approx5 voltage drop "C" and body ground: voltage drop "A"
