Parasitic draw/drain

[Aucomo]

Greetings,

First off this Toyota is my wife's car and im use to working on my older trucks (76 Cheyenne w/454 and 86 silverado w/379 diesel) that being said, im not really the best at electrical issues with newer stuff.

Basic background of the issue and what lead me to here:

The car had been running fine and then one night she forgets that she had her key in accessory, few hours later and the battery is dead. I go and jump start the car, let it run for 10 minutes or so and call it a day. In the morning the battery is dead again, had the battery tested and replaced since it was defective.

But i still had a hunch this was bigger than just a battery issue, i tested the alternator output and it came to about 13.8-14 (alittle low i think) and then i tested for a parasitic draw.

Thats where im alittle fuzzy, dc current doesnt really change that much from vehicle to vehicle so i did this test the same way i always do it. Pop the negative lead off the terminal and hook up the multimeter to each end of the negative side, when i do that it reads 11.8-12.1 volts. So correct me if im wrong but this is not how the yaris should read.

To try and find the issue or location without wire chasing, i test the tops of the fuses and see what they say (with battery installed). Everything was pretty low except the abs1/vsc1 fuse. I pulled it out to check the posts and it was reading 12ish volts.

The part that confuses me is with that fuse pulled and then i do the draw test again i still get the same reading as before. So im not sure if its an issue prior to the fuse box or what any help would be appreciated 🤙
