    INSPECTION OF PARTS Capacitor 1. Ohmmeter method Set the ohmmeter to the 10M range. Place the two probes against the two terminals of the capacitor. At first, the ohmmeter should indicate a small value, and then the reading should gradually increase towards infinity. This indicates that the capacitor is charging. If the reading indicates infinity immediately (open) or the ohmmeter fails to move from 0 (short), replace the capacitor.
