Computer and System Circuit MEASURE VOLTAGE OR RESISTANCE OF SYSTEM Using a volt/ohmmeter with high impedance (10 kΩ/V mini- mum), measure the voltage or resistance at each terminal of the wiring connector. NOTICE: To prevent damage to the computer, be care- ful of the volt/ohmmeter range and do not connect it in reverse.
