50Amp - Brake pump
50Amp - Engine cooling fan

The other battery positive cable goes to the starter and then on to the alternator. So, essentially, the entire car's electrical system is fed thru that box, AND, other than cooling fan, brake pump and alternator, the entire car is fed from the 200 amp fuse. Since almost ALL current flowing ("parasitic drain" or otherwise) flows thru that 200 amp fuse, of COURSE you will measure current going to it.

It is easy to pop the cover off, do so, you will see that there are only three fuses in there. The only way current can "leak to ground" in there is thru the plastic body of the box itself.

But since I like watching people learn, I encourage EVERYONE with a battery drain issue to replace that box. Do it first, then report back to this forum with your results.
Correct me if I am wrong but admittedly I am not a mechanic or an electrician but I wasn't aware that plastic conducted electricity, I am aware that it may be attached by some conducting type of screws but seems like a bit of a long shot humbly in my opinion, but I also would love to thank you for explaining exactly what it is that the box is exactly used for and this is the only thread I have found with any references to this box. I am a xfire newbie and although the engine seems and sounds brand new imo I do have a number of issues that seem unrelated, I'm actually in 2 minds sadly to selling the car as spares or repair as never had as many probably easy fixed issues, the seats being full electric and for an 05 look better than most I've seen in cars a quarter of it's age easily. The power of this car is from the great mechanic in the sky and after driving many different cars over the years this in 1st 2nd and third is insane, I just wish I could find someone who could sort out the issues it seems to have. Would an ABS ring repair more issues than I can imagine or is that another false piece of info I've been given, the manual box is a dream too. Battery draining is something I have not come across B4 ever in 32 years of motoring. If anyone reads this and has time to go over a few things with me I will be forever indebted to the people who are able to help. Thanks everyone hopefully someone will get back to me ASAP.
