Default 2004 LS draw on battery

Hello thank you for any help. I have a 04 Ls 430 that runs great. I use the car daily but it sat about 2 weeks. When I got in the battery was dead. I charged it and again it was dead the next day. I bought a new battery and from fuse #66 D/C out I was getting a 10v draw while the car is in sleep mode.That fuse powers fuses MPX- B1, MPX- B3, MPX- B2. If I pull out all three of these fuses the draw stops, but if I take one single fuse and put it into one of the three spots, I get a draw, but it’s only 10 V when all three are plugged in otherwise they’re about 3 V for each fuse. i’m a little lost. I’d appreciate any help. Thank you.
