Hello, the main fuse is actually incorporated in a modular fuse/link block, you should see it in the fuse box under the hood, it's white in color and has a transparent cover, it is bolted in, most likely there are a couple of segments burned out so you'll have to replace this entire fuse assembly. I'll see if I can attach a picture in a few minutes.
It's losing power between the fuse box in the engine compartment and the fuse box on the inside, this means that there is a blown fuse or fuse link in the box under the hood, there should be battery voltage to the 10mm post with the nut on it, almost all power from the battery goes through the fuse link to the other circuits and to the fuses inside the car.
It's bolted in with the 10mm stud and nut where the large wire from the battery coonects and there is another bolt on the side at the other end
There are also plastic retaining clips that you can depress to release it
You will have to partially disassemble the fuse box to get to the other bolt, the fuse sub holders have snall clips on the side, you should be able to depress them and pull them up so you can get to the bolt.
Just around the link so you can get to the bolt, I believe it's on the right side looking at that picture/
Ok, unfortunately the Toyota factory manual doesn't give instructions on how to do this , although I have replaced a few of these types of fuse links on Camrys where the fuse box has to be removed and taken apart I knew that it had to be taken apart at least partially, I haven't figured out a shortcut around this.
If it doesn't fix it just let me know and we can continue from there.
