Using a car battery and connecting + and - at each side of the fuse is enough to blow the fuse instantly.
(wouldnt do it with the used car battery in the trunk, or atleast completly disconnect before)

I have a marine battery in my garage, unhooked for winter storage. That should do it. Thanks.

If the OBD got no power with ignition on then they use external power, a broken fuse wont help for sure. Otherwise this would be an insanely good theft prevention without any costs.

See my post above. The ignition doesn't even need to be switched on for the OBD to have power. It must have constant power, because my OBD reader powered up without even touching the ignition switch. But removing the fuse completely removes power from the OBD port, even when the car is started (which I tried). The car starts just fine with the OBD fuse removed, and the only message on the DIC was that the trunk was open.
