How do i find that main fusable link?

What is the real issues?
Not many vehicles, have anything called a main fuse
Fusable links,have been replaced with large fuses,
those will be in your owners manual

check master fuses and look for a power junction where multiple cables and or wires are joined. there maybe a fusable link involved.to check a fusable link you pull on them ,they will pull apart. just replace the fusable link .

Check the main relay

Check main fusable link or fuse (on small wire from + battery terminal

does the main yellow wire have a fusable link in it, if so it might be blown,

When a fusable link burns, it is an indication of a dead short to ground. With that said you have to find the short to repair the problem. This can be tedious and time consuming. A wiring diagram for that circut will be an asset. Wish you success in finding the problem. PS Has the radio been replaced lately? I will check back on the 14th.

Your vehicle may have fusable links that connect to the large terminal of the starter (the terminal that goes to the thick wire to the + of the battery) they may have been broken if stretched by tisting the terminal or if the starter hung from the wires ... or if they were shorted (they are burnt inside) check them with a test lamp (where the black rubber blob is before it connects to the harness not at the bolt side) about 8 inches away ... there is generally another (or a couple) fusable links located on the firewall (pro jobber parts shop will have these replacement fusable links) ... that connect to another fat wire from the battery ...

check the inline fuses at the battery they carryu the main power they are a fusable link good luck Lindz

could be a fusable link in the wiring harnes near the battery box/check all links

This sounds like a loose or bad ground cable. This can be checked by attaching negative side of jumper cable to engine and negative terminal of battery. If this solves problem, replace cable.
