Naaah, you're wasting your time doing it that way -- and you're only going to fool yourself with the results. Measuring resistance will only get you so far. For example, let's say you have two wires, one is a nice new fat 0 gauge battery cable and the other is a ratty old piece of copper strand the thickness of a dog hair. You get out your trusty multimeter and you check the resistance on both wires and they both show just about no resistance. Maybe the dog hair is actually a little less in ohms, who knows. What does the test tell you? Nothing. The moment you put a load on the dog hair the wire will go
*poof* and you'll have an open circuit. In order to really measure a "thing" that is on an automotive circuit, be it a span of wire, a circuit breaker, a fuse, a connection, etc., you must perform a
"voltage drop test." That's your next lesson after you master clamping your inductive amp meter around a wire.
