F200, in the main fuse bank above the battery? Yeah, if that was popped, you'd have zero power to a lot of the car.

It's upstream of F105, feeding F105, so your fault current is running through F105 but (good news), your fault current is less than 200 amps (but more than 60 amps).

Actually, most fuses have a fuse rating of something like 2x the stated current, i.e. it takes 120 amps to blow a 60 amp fuse. A 60A fuse can safely carry 60A continuously but it take quite a bit more to blow it.

So you have a BIG current sink somewhere. And I'm guessing that 60A fuses are too expensive to just keep disconnecting stuff until it stops blowing.. so we'll need to get a bit smarter on fault finding here... Putting my thinking cap on...
