Shortening a Fusible Link

Hi TC,
I need to replace a terminal on a fusible link going to the alternator. Instead of buying a new fuse link, can I just cut of about 1/2" and resolder a new terminal. By doing this, will I be affecting the rating of the wire?
Thanks in advance, Paul.

Re: Shortening a Fusible Link

A fusible link, when it boils down to it, is just a wire that is a little undersized for the current, so if the current gets a little too high over a given short period it melts.

Somewhere here, and cant find it in my library at this piont, I have a conversion of automotive wire sizes/ rating/ lengths which can be used to make ones own fusible links.
I have not googled it , so go down that route to.
Never include a fusable link like this in a loom.

My Spelling is not incorrect...it is creative

Re: Shortening a Fusible Link

Yes, but I would crimp this connection and not solder though.
I've seen links that are aluminum, so crimp for sure.

The FL's have a somewhat fireproof jacket, but they sure can produce a big smoke ball.

Thanks for your responses. I'll go ahead and use my current FL cut about 1/2" and re-install a new terminal.

Thumbs down Re: Shortening a Fusible Link

1/2 inch shouldn't cause a problem and I would solder it. Soldering decreases resistance as current flows thru the connector and it will keep the copper wire from oxidizing. Be sure to buy high quality tinned copper connectors. Do not use the cheaply aluminum connectors.

A fusible link is more than a slightly undersized wire; it is made of a special alloy and is meant to burn once it reaches a certain temperature. When you get an electrical overload, all of the wires in the circuit heat up, the fusible link burns and breaks the circuit. The wire cover is also a special material meant to contain the burn as much as possible. As Steptoe said, never bundle or wrap up a fusible link with other wires.
