Thanks for catching my error (again ). I've edited my original post. Contrary to the wording of my original post, I was only thinking of the general "custom circuits can't affect power pathways" rule and forgot the exception for low-impedance current monitoring. Presumably (0.075 volts) / (200 amperes) = 0.000375 ohms is low impedance...

Oh that makes sense. I was reading the 12V as a safety rating or something along those lines.

Well it would be good to check the rating on the multimeter first. Not worth blowing unnecessary fuses. Also make sure that the probe leads are large enough to handle the current as well.
