i have a parasitic battery drain in a 2012 lexus, is250c. so far, narrowed it down to the #7 fuse (10A) on the passenger side, engine compartment fuse. it controls among other things i guess is, the key fob used to open the doors and trunk, gas filler door, and trunk latch. Lexus dealer has not found prob yet.

That draws quite a bit of current if you have the fob near the car.
How much current is being drawn through that fuse?

I work for ALLDATA so I looked this up. D/C Cut, a 20A fuse feeds in passenger side junction box by the right kick panel. The affected circuits are:
I attached some pics. I'd check the dome lights and make sure nothing is switched to the ON position.
- Dome - 10A
- MPX-B1 7.5A
- MPX-B2 7.5A
- MPX-B3 7.5A

LS430 if the D/C cut fuse both sides have power and not getting to the passenger side fuse box there is either a connector unplugged or broke wire. Another thought here is it is difficult to find a good ground for your test meter at that fuse box. Make sure you have a good ground in testing to make sure voltage is not there. As you can see from the diagram it is a direct path to that fuse box through connectors. What I would do at this point is disconnect the battery and put multimeter on ohms and see if there is a short at fuse box. If no short hook battery back up and trace wire backwards to find open or simply put a wire from the fused side of D/C cut fuse to that point. This is the diagram I would be looking at to help you.
