MPX-B fuse
I've searched previous threads but couldn't find anything to solve my problem.
Something is draining my battery. My mechanic tested and found the fuse under the hood (1998 GS300) labeled MPX-B is drawing current constantly. Does anyone know what this 10A fuse is associated to?

Fuse MPX-B Parasitic Draw
my 2007 ES350 keeps killing the battery. I measured the parasitic draw at 70 to 80 ma. Anybody know if this is normal? Online forums suggest 30 to 50 ma to be expected. The fuse under the hood in slot # 34 is a MPX-B 10 amp fuse labelled "meters" in the manual. It alone draws about 30 to 40 ma. What is on the "meters" curcuit?

Shoot, even after finding the fuse for the system drawing amperage, you still have a lot of areas to check. That's a lot of stuff protected by that same fuse! My first suggestion is to go to all of your doors, seats, sunroof, etc. and make sure there are no switches jammed on. Activate everything and see that everything works and stops working when you stop pressing on a switch. Make sure the door switches are registering that the doors are closed. After basically switching everything you can, check again for amp draw. Maybe you will have unstuck the switch. Power seats and radios are a common amp draw from what I've seen.
