I would start going through the smaller fuse panels pulling one at a time until you find the circuit the drain is on. From there you can narrow it down more. Do you have an after market alarm/remote start? May want to start there.

I think you need to do a parasitic drain test , I used to test shorts from continuity but apparently not the right way

I had same problem. Did all tests I could think of and several Mechanics could not find it, so I went back to the basics replaced my ground and I found that if I put a 3rd ground to my frame all my electrical problems went away . Even my odometer lights go off . So try it .
