You aren't supposed to test resistance on an energized circuit. That's where a voltage drop test comes into play. Resistance is like a static test for an unenergized circuit, a voltage drop test is like a dynamic live circuit test.

Using Ohm's law, you can determine resistance between two points in a live circuit when using the voltage drop test.

What type of issues are you having? IMO while ohm checks have their place, once you energize(complete) a circuit, you have introduced current flow into that circuit.

There are cases where a wire may test perfect during an Ohm test(0 Ohms) but when energized, may allow a huge voltage drop due to(for example) having only one strand still intact. In this case a resistance check would yeild perfect specs, but a voltage drop test would nail it.
