Yea, some MMs are multi-setting and not auto-ranging (auto-detecting). You want to put the rotary switch to any setting just over 12 volts. As long as the setting is not under 12 volts, but it should be the setting that's either exactly 12 or the one that's one increment over it. Should be fine.

To clarify the method, though, when testing for live voltage (as in your seat power harness) you must use the volts-DC setting (as above). Do not ever allow the multimeter act as a shunt or shorting device between + and -. In other words, don't let the red and black lines touch one another, either directly or through a multimeter lead or leads. Keep the hot and ground isolated from one another at all times.

When testing for continuity, as with a removable fuse, pull the fuse. If you want to test for continuity with the fuse still installed, disconnect the battery. You can't use an ohmeter to check for resistance and/or continuity with power applied across the circuit under test - you could blow up your multimeter or damage the circuit.

it can also cause problems if you are touching the metal portion of the probes or wires as it will change the resistance when you are hot/sweaty. It can be challenging to touch just the wires and not the probes with your hands and why all of my meter leads allow me to screw an alligator clip to them.
