04 Tahoe blowing fusible link in fuse box for starter
My 2004 Tahoe wouldn't start on Sunday. Check battery and starter, but it turned out that the 40amp fusible link in underhood fuse box was blown. Replaced and it started immediately. Drove for two days and went to start it on Wednesday evening and it did it again. Replaced fuse and started immediately.

Year make and model helps. Older cars have fusible links. Might want to check them. And fusible links can blow( no power) and blow some what and show low voltage at the panel. Most links are at the battery or the starter. They look like the wiring, except they are bigger than the wires the run with. Different colors also.
There is a starter fuse that is not located in the fuse box, it is actually a fusible link mounted as part of the battery terminal. As a check you can by-pass this with a short piece of wire and try to start. This fuse blows easily for example if someone tries to start the car when it's in gear. Hope this helps.
The fuse box by the battery should be directing power to the fuse box inside, either through a maxi-fuse or a fusible link. Check your maxi-fuses, if all are good look for a blown or melted fusible link. If still no help, consult a wiring diagram.
Sounds like a fusible link burned out. Check the wires at the battery cable post of the starter. The smaller wires connected here are the fusible links if equipped. If not then check where the smaller positive cable off the battery goes to the fuse box. It will be connected to fuses there which could be burned out.
Start by checking all of the fuses and all of the fusible link wires, and you will know a fusible link wire when you find one because they will stretch similar to a rubber band. Fusible link wires are usually located at the fuse/relay junction box in the engine compartment, or at the starter solenoid, or sometimes at the fire-wall. Also check the fuse/relay junction box for any PAL type of fusible links.
there may be a high amp fuse blown or a fusible link blown. check all fuses in the passenger compartment and under the hood. if you find no fuses bad, a fusible link is a large red cable that has a fuse in line. check the red cables leading from the battery to the starter for bulges in the line.
My 2004 Sebring did just that. it was a fusible link. a tiny square box in there with the fuses. they are a cube that plugs in about 3/8" of an inch square. Find the bad one replace it and the starter starts working again.
It would either be under dash or on side of kick panel, or behind or under glove box. Also under hood in black box on firewall.
If you find the fuse and it is good, than I would check the fusible
link that runs off battery and heads to ignition system. The little
black fuse inside fusible link can blow while jumping or connecting
battery cables backwards.
