eliminating fusable links

[brianj]

Has anyone successfully eliminated the Fox fusable links and replaced them with regular fuses? I had thought i had seen some posts about this, but my search fu seems to be weak, since I can't pull up any info. Can anyone point me in a direction to look this up?

I'm going to do it with maxi fuses this winter.

Here are a couple of threads where i discuss it. The first is titled "Eliminate Fusible Links" of all things.

I actually saw that, i was just wondering how it worked. I'm actually reconsidering it, doing some research.

I'll let you know! I'm sure there's nothing wrong with fusible links. I am just more familiar with maxi fuses, and using them would make that area a bit neater and therefore make me happier. Probably sometime in the next month, I'll do it.

I'm much happier with fuses. However, from what I've been finding, it appears the manufacturer used them for a specific purpose - if there is a sudden voltage spike, like electric fans coming on, for example. A fuse that is large enough to handle the spike will be too large to keep the wires from meltdown. Fusable links heat up from the spike, but then cool down and are undamaged. A fuse that takes a spike weakens, and will not hold as much amperage. As much as i would rather have fuses, i think I've talked myself out of them. I found a bunch of info- it helps if i spell it correctly in my searching. Fusable vs fusible.

Not for everything, but yes for the eliminated EEC-IV/CFI stuff, lol, and yes for the electric fuel pump. Fusible links are too "black box" for my liking. A blown fuse is a blown fuse, no mystery or confusion there. Unless there's a problem with the electrical item, I don't believe anything spikes over it's rated maximum amperage, which, like a short circuit, is what melts wires and creates fires. Common best practice for fusing is to use a fuse with an amp rating of approximately 135% of the item's rated maximum amperage.

And use relays for things that spike like fans. For all of my fan power wires (there are four of them--relay coil power, main power, 2 relays), I used automatic circuit breakers.

Modern cars don't have fusible links for anything. That's good enough for me.
