Apple fuses don't **** normally. If yours is ****n I would do resistance tests and check out the circuits before applying power. What ever you do don't use a jumper wire!

Jumping the fuse in a last ditch attempt to get the backlight working when you have no interest in learning about the basics of board repair is acceptable in my book. In most cases you aren't going to make matters any worse, but just know that it's not usually the fuse, especially if we're dealing with an A1466. Pads 3 & 4 on the display connector are most often what you will need to fix, they are almost always burned/damaged after liquid exposure. If those pads look nice and shiny, no obvious damage, then you might suspect the fuse, and if it's not the fuse, it's might be the backlight driver but we're now at the point where even macgyver might throw in the towel
