Remove each fuse one by one, put your amp meter, actually a digital voltmeter or an analog one for that matter, and put the probes across the contacts. Measure the amperage and write it down. Look at the resulting table and see which one has the most current. See what systems are on the circuit in question. You can post the results if necessary so we can help you. Modern cars use lots of electricity for things like engine computers, climate control computers, transmission computers, instrument computers, body computers, stereo systems, which are little computers... You get the idea.
