that means you're not metering right lol. IDK if you know the difference between a short and an open wire, so bear with me lol. Are you metering for power? or to see if there is a short? Because thats 2 different ways. First, I would see if the maf itself is still good, you know the male pins on the maf, find out which one is the ground, and which one is the power for the maf, touch the black lead on one pin and the red lead on the other pin, and make sure you have your meter in ohms, if you get a reading(which I'm sure the maf has a resistor in the honeycomb, you should see it) that matches that resistors value, then I would say your maf is good, its not shorted out, BUT you still need to find that short in the power wire or ground wire for the maf. so, what you want to do is meter from the maf connector(harness side) ground wire, and put the other lead some where to ground on the vehicle. You should get a reading of anywhere to 2-10 ohms I would say, BUT if you get 0 ohms, thats your short. if your ground wire is good, then you need to go from the harness side for POWER, without power acutally being there, and go to where the power comes from (aka fuse box, or ecu plugs) and make sure that the power wire is intact and you get some ohm reading. once again, 0 ohms is a short, and O.L. which means over load, out of limits, means you have an open in the wire. sorry for the crash course in electronic principles, its hard to explain in writing.
