A single strand of wire from a group of conductors will produce zero resistance when checked with an ohmmeter. And that single conductor strand may create enough resistance to prevent the circuit from working properly.
An ohmmeter isn't the most appropriate gauge to measure grounds. How could you accurately measure a suspected ground connection with an ohmmeter? BTW, ohmmeters don't like live circuits. It can let the smoke out of the meter.
Use a digital multimeter and check the voltage drop (the amount of voltage loss between two points in an active circuit. Connect the voltmeter leads to either end of the circuit to measure (not including the load), then switch the circuit ON. Voltage drop should be typically less than .1 volt.
