6-8 EXCESSIVE COOLING OR HEATING.6-9 A SENSOR IS DEFECTIVE.36
7 CHECKING ELECTRICAL COMPONENTS7-1 Measurement of Insulation ResistanceThe insulation is in good condition if the resistance exceeds 1 MOhma) Power Supply WiresClamp the earthed wire of the power supply wireswith the lead clip of the insulation resistance testerand measure the resistance by placing a probe oneither of the power wires (fig.1).Then measure the resistance between the earthedwire and the other power wires (fig.1).b) UnitClamp an alluminium plate fin or copper tube withthe lead clip of the insulation resistance tester andmeasure the resistance by placing a probe on N terminal,and then on Lterminal the terminal plate (fig.2)c) Measurement of Insulation Resistancefor Electrical PartsDisconnect the lead wires of the disired electricpart from terminal plate, PCB assy, capacitor, etc.Similary disconnect the connector. Then measurethe insulation resistance (fig.1 to 4).Refer to electric wiring diagram.NOTEIf the probe cannot enter the poles because the hole is too narrowthen use a probe with a thinner pin.37
