Fuse/Fusible link in wire from alt to batt?

[samckitt]

What are you using to protect this circuit? Are you using a fusible link, or a regular fuse, or something else?

I may need to change some wiring. I have a wire from BATT+ to the charging post of the alternator & from there to the GMPP harness fuse box. And in this fusebox I have added a circuit for the cooling fan. Not exactly sure yet how much amps it pulls, 50ish(?).

So if I put a fusible link near the battery in this circuit, will the cooling fan kill it?
