TOYOTA , LINK COLOR CODE FUN.
WHICH LINK NOT TOLD.(EXACT LOCATION)
I GUESS , ALTERNATOR DEAD OR WHAT?
ALT FUSE 140AMP FL ?
FL-MAIN?
how to buy it or just how to physically attach it.
what I do is upgrade it to a real fuse, at same rating
as LINK, COLOR CODED SPEC.

BEST ANSWER (IF YOU GOOGLED)
toyota does not have disassembly instructions for the fuse boxes.
the word link means , not just plugs in.
it is wired in or crimped in or has studs
no fuse told yet just vague words.
there are at least 6 fuseable links there.

why not ask here

it is in the positive battery cable go buy one at your local auto parts store

Yes fusible links are replaceable. Go to the auto parts store .

you have a dead short in head lt wiring. try un plugging one head lt at bulb at a time. if continues to blow fuse inspect wiring in cicuit for any bare wire too frame.

I don't see how the engine overheating could have been involved since all three components are on different circuits.
Unless something happened to a power source under the hood such as a fuseable link wire.
You will need a book to find the wiring diagrams to test the circuits.
Sometimes you can get the diagrams from the online auto parts stores such as auto zone.

Hi and welcome to FixYa, I am Kelly
You have a fuse link/ Fuseable link) in the wiring from the battery to the fuse box that has probably failed. Go to any auto parts supply Napa, Auto Zone ect that has computerized parts break downs of your vehicle and ask them to show you where the fuse link is located. It will be inside the black plastic conduit material of the chassis electrical harness. Some Vehicles have more than one Fuseable Link. Make sure to ask when you check at the auto parts source if there is more than one and ask for the location of that one also. Most auto parts stores will show you the computer monitor with the location diagram of the Fuseable link.

check voltage on your battery. good charge? check connections to your starter. good connections to the starter? check for a blown fuseable link between the battery and the starter. a rubber type link thats hard and will break in two when pressures applied. it will be between the battery and the starter[electrical] [wiring} that's what it appears to be to me. a blown fuseable link in the wiring. the complete book can be purchased at any autozone or advance auto parts store for about $20.00 i bet if you charged your battery for free at either one of these parts stores,your truck would start on it's own. try this and see if i'm right or i'll buy you lunch. thank you for choosing fixya,com!

if none of them work look for a master fuse in the fusebox, or even a relay or fuseable link under the hood. your local auto parts store might be able to tell you the location of these

yes the the ignition and fuel pump are usually on the same fuse or circuit, check your fuses, if you can get wiring diagram of the two circuits it may show you if there is afusible link, they are a bit more of a pain to find, in the miles of loom in a vehcile, but they are usually located close to the battery or the fuse panel. most of the time they are grouped together with the other fusible links. Does this truck have the duel tanks before and after the axle, make sure the switch is working corectly too.

I don't believe there is a main fuse.Chevy uses fuseable link wire that come off the starter.They are like fuses,but they are wires that are made to burn if overloaded.Pull lightly on the wires coming off the starter & see if one or more stretch.This indicates a burnt fuseable link.You can buy fuseable link wire at Auto Zone cheap.Good luck,
