93 Jeep Wrangler Parasitic Drain

You mentioned forest for the trees. You KNOW what circuit it's on

I assume you are measuring drain current at the main battery lead so as to measure "all" draw?

Keep in the back of your mind "you sure" your multimeter is correct? As much trouble you are having, might be worthwhile to check

Otherwise, it's the painstaking job of checking every single thing on that fuse. I think my first test would be to unplug the engine computer.

Some other thoughts:

How long does this take to kill the battery? 70ma is really not all that much, but IS more that "normal" should be. Some cars seem to drain at about 30ma nowadays..

Was the battery actually load tested? What did this show, IE amp hours, etc?
