Newbie's and Multi Meters

actually, that would just blow the internal protection fuse (done it before) but if you were to test voltage with it in the amps scale, it presents a dead short to your voltage source, it'd basically be like putting a piece of wire across the source, at 600 volts, things explode and people die. at 12 volts, with a battery, you can fry your meter and it could explode as well.

ah, multimeters, such a deadly little toy.
i was working on power for my laser, checking resistance in the connections and my boss decided to unplug the test lead from the ohms plug-in and put it in the voltage plug-in.
i hadnt noticed the change and touched the wires.
i tell you, i havent my pants since i was about 5, but that day was very close.
450 volts can be spoooky.

in a car environment, I don't see the huge danger, well anymore than doing anything else on the car that you aren't capable of doing yourself...
A brake job gone bad, could land you sailing off a cliff too, but it all comes down to knowing how to use the tools you have, and what the effecs are of misusing them.. I think anyone interested in educating themselves in the proper way to use the tools, and most 'accidents' are avoided.

that's not impedance, that's resistance, using a resistor, it's resistance. impedance is the total circuit impedance caused by the inductance of the coil, added vecotorally with the resistance of the wire
