To find an open ground in wiring, follow these steps: First, turn off the power to ensure safety. Use a multimeter set to the voltage setting and check voltage between the ground and a known live wire. If the reading is zero, the ground is open. Next, set the multimeter to the continuity setting and test between the ground wire and a known good ground. Lack of continuity confirms an open ground. Always ensure power is off and consider professional help if unsure.
