5.61 amp battery drain on 2000 3.2tl

What could this be? I pulled one battery terminal, connected my multi-meter on amps DC and pulled all the fuses and relays (one at a time) with no change in current draw. All lights, radio, etc. are turned off. I’ve read that some Acuras develop a current drain that is hard to find? Any ideas?

Disconnect the heavy “charge” lead from the alternator…
