Brad, when measuring voltage drop, "nothing" is good. You do need to make sure you're getting a good contact with your probes, which should be obvious as the meter display will settle down when your probes make contact. If there's no voltage drop, then the meter should show only a few millivolts.

Always use the same ground, preferably the negative battery post. I expect you'll see the voltage fluctuation everywhere, but if you don't it will give you a clue where to look. If you DON'T see any voltage fluctuation, the the problem isn't in the charging system; more likely a bad lighting ground.
