Who knows? Not enough data to say.
First problem is Alt max/peak Amp output, Alt output Wire Size, etc can affect the fuse or fusible link choices.
Too low fuse can have "false"/"nuisance" blows. Nothing wrong but the wrong fuse.
Too big fuse can have a fuse refuse to blow and then the main wire will heat fast often causing a fire.
Both that can happen on the highway.
Using OE harness but what alt and what's eating that power? Bigger amp alt might need to replace OE wire because can't handle extra power.
Second is
Link/Fuse is not really there to protect the Alt etc. Is to stop the battery from dumping 200+ amps to a short circuit. That's why most fusible links are near/at the battery + terminal on any vehicle.
There are easy rules to correctly size links to wire to protect. Very short... Link is smaller gauge vs wire to protect and about 6-9 inches long.
As for "Fuse Links are Bad" myth? Billions of vehicles have Fusible links and
never have problems. Some love to replace links w/ maxifuse. They most likely are not qualified to say fuses are good plan or what amp value to meet demands on a given circuit and wires use by the cuircuit.
Max Fuse may be "better" or not depending on the application... Many cars w/ Maxi Fuses still have Fusible links too. Links are "last line of defense" from battery melting down the wire harness. Others w/o links have Maxi's and others very close to the battery.
Very few Real Experts and Engineers replace fusible link with any type of fuses or breakers for safety and liability reasons. Fusible links are still use worldwide in many applications including automotive. Fuse makers like
LittleFuse and Others won't give you data because they
Cannot tell you what Maxi fuse can safely replace Fusible links.
Properly installed Fusible Links rarely cause a problem. Plus Water Resistance is easier and needed because Fiero power dist "box" is in a very wet area. Most Maxi and other Fuses hates water and need a waterproof socket and cover for use in Fiero engine bay.
