I went with a powermaster 140amp alternator with a heavier gauge wire to the battery. I need to install a new fuseable link, and was wondering what kind of amps I need. Do I just go with a 140amp link? I'm sorry if this question sounds dumb. Thanks!

I don't think fusible links are rated by current like fuses are. You choose them by wire gauge.

Years ago (decades ago) I was told by an auto electric shop owner to choose a fusible link 4 gauges smaller than the gauge of wire of the circuit you're wanting to protect. If you want to protect a 14-gauge wire you would use an 18-gauge fusible link, for instance. And to keep the fusible link shorter than 12" or so.

Thanks for info. This is the part i'm referring too. The black cylinder in middle of pic.



don't mind the cobbled wiring job. I'm in the process of doing it right this time.

That black thing is just a factory crimp cover. The fusible link is the wire coming out of the top left of it.
