Glove box light or any interior lights curtsey lights boot light that might be stuck on. Radios and or any other added accessories. Un plug alternator ect and do the following test.
This is a fairly simple test to find what circuit is drawing power if you don't have a current clamp meter.
Pull the negative off the battery. Put the test light between the post and the ground wire you removed. If the light illuminates, you have a draw. Pull each fuse individually when the light goes out, you have found the circuit with the current draw.
It gives you a starting point and a area to look at once you have narrowed it down other wise u will be pulling your hair out trying to locate it
