Anyone know where I can find a 8AWG fusible link?

I can't find a supplier for a 8AWG fusible link for my alternator wire. I've found a few that sell reels but no one that sells a 9"-12" piece separately at a reasonable price. Anyone have a link ?

yes I know stock is 10awg but I upgraded to a 160 amp alternator and I want to upgrade the wiring as well. A 160 amp alternator needs a 8AWG.

Thanks for replying

A 50' reel is $75 so I'm finding it quite a markup to sell a 9" piece for $30-$35. The first link only sells 25' lengths. The second link is $30 but they want $20 for shipping which is ridiculous. I haven't checked the 3rd link, I'll shoot them off an email and see what kind of shipping they want. Thanks for the links

Keep searching. That took me 2 minutes to find. There must be more places.

Good Luck.

I have been searching the net for that last week LOL, a 8AWG fusible link is like finding a 4 leaf clover. Must be rare but many vehicles use them, its weird.

It may come down to how much are you willing to pay to have it. I'd try calling those links and see if they just a foot of it. If they have spools, they may have inches and not put it out there for people to know.

A fusable link is nothing special and it isn't actually a fuse, it is typically nothing more than a piece of wire that is sized four gauges smaller the wire it is protecting. It has an extra protective sheath over it for when it melts but that's about it. http://en.wikipedia.org/wiki/Fusible_link

Everything I am finding says you should be using a 12AWG fusible link for an 8AWG charge wire from the alternator.

Try figuring out what size you need first and then see if it's available.

Thanks for all the input guys,

Mr. Blaine I've done the research here and here. I started this thread just to find a cheaper supplier of these 8 AWG fusible links.

Just FYI, For a 160 amp alternator swap all the wires you require a #4 AWG wire from the alternator to the battery and also the negative wires of the battery and a #8 AWG fusible link on the wire going to the alternator. I'd rather go to the junk yard and get a complete harness but here in Eastern Canada we are getting pommeled with snow storm after snow storm and all the junk yards are under 5'-6' snow. I was thinking if I can get a fusible link I'd make my own wires but if its going to cost so much for the fusible link I might have to wait till the snow melts

Jerry your right a fusible link is just a wire but the insulation is special so it doesn't burn and stays intact when the conductor melts under fault.

Why not just use a regular fuse? The only reason OEMs use fusible links is sometimes they are cheaper to implement. Just pick up a cheap ANL fuse holder (audio supply store) and mount it somewhere near the alternator.

Well I want to go with fusible link for a number of reasons, a fuse over time when exposed to high loads can become fatigued and fail. Another reason is what is the size of a fuse that you would need that would protect my battery? I work in the electrical field and its quite a calculation to properly coordinate fuse timing and at what fault level. It isn't 160 or 170 or even 200 for sure because if you put a 170 amp fuse and your running at 160a the fuse won't blow but you'll get a voltage drop across the fuse which is problematic. A fusible link is designed to sustain an overload for a period of time, it acts like a time delay, whereas a fuse will act too fast and cause false trips. A large 250a fuse is $40 here in Canada. For all those reasons I don't want to use a fuse.

I think you are overthinking this, most new cars use standard fuses and not fusible links, but do whatever makes you happy.
