Hi, in some European Toyota models they have hooked next to the positive terminal a plastic armored box and there are fuses that to repair them you have to change the box or weld them, perhaps in the American models they do not take it. While your model carries these fuses in the engine compartment box, they are fuses that are screwed and to change them you have to disassemble the box.
I send some files in JPG.

I had already changed it ... it was the alternator just .. They burned all the diodes .. it is the system that is screwed ... very good scheme you have .. well realistic .. I have already solved the car and it was perfect back ..
