Fuse/Fusible link in wire from alt to batt?

[Black93GT]

Maybe I'm misreading it, but from the sounds of it you have two forms of protection inline with each other on the same wire???
Alt----FL----Fuse-----battery------fuseblock


The two provide the same type of protection but with different applications.

The fusible link works like a slow blow or time delayed fuse. It allows you to hit the max amperage and stay there for a rated amount of time. Also, due to the slow action, it can handle some over current as well. This makes them less prone to burning out.

Your normal fuses are fast acting, so once they hit the rated amperage... pop. Not unreliable by any means, but their priority is the protection of electronics.


The fusible link should go near the battery for both easier access and to keep it away from direct engine heat. If your fuseblock doesn't have a large main fuse you'll want to use that maxi fuse to protect that portion of your electrical system.

ALt-----FL--Batt---fuse---fuseblock

Personally, I like to have the big fuse close to the battery as well. I'm not a fan of leaving a long section of a high current conductor unprotected but there's nothing written in stone.
