Fuseable link in alternator charging wire 98 gmc
 

I am replacing all the power, ground and charging cables in my truck with larger gauge wire while I'm wiring it up for dual batterys. Last thing is the charging wire from alternator to the battery. It has a fuseable link in the factory wire, which I will replace with a fuse holder on my new cable. My question is, what amp is the link?

I don't know but wire size determines max size fuse. A lot of people don't realize but a fuse (in most cases) is to protect the wire from overheating. So the max size would be determined by the wire size.
