Fuse wire From alternator upgrade need help

Hello everyone,

I just upgraded my alternator and the company that sold it to me said that the cable had also to be changed to 2 gauge. So went ahead and replaced the cable but noticed that there is a wire fuse (someone told me that it is a cable that works as a fuse and has silver in it or some sort of material, this cable runs from the alternator to the fuse box which then runs to the battery) anyways I changed my new cable to 2 gauge, can anyone fill me in to what cable fuse should I buy to place the fuse cable or what to do to protect the battery in case the alternator goes wrong?

thank you!

It's called a fusible link.

From Wikipedia
Quote:
An electrical fusible link is a type of electrical fuse that is constructed simply with a short piece of wire typically four [American wire gauge] sizes smaller than the wire that is being protected. For example, an AWG 16 fusible link might be used to protect AWG 12 wiring. Electrical Fusible links are common in high-current automotive applications. The wire in an electrical fusible link is encased in high-temperature fire-resistant insulation to reduce hazards when the wire melts
I'd like to hear more about your 205A alternator...

Thanks for the info from Wikipedia. Finally that resolves my problem.

You'll have a hard time finding 6AWG fusible link wire anywhere (I've been looking for 10AWG for years!)

Use a 225A ANL or MEGA fuse instead. I can help you there if you like - link in sig.

thanks, your right, best i could find is 10 gauge fusible link, perhaps adding the 10 gauge and the MEGA fuse or ANL will have a better protection.
