[QUOTE="jrwalte, post: 4928018, member: 584454"] I also don't fuse the alt to battery +. I have it in a loom that resists heat and I ziptie it to secure it down. Always keep your wire secured 2-3 inches away from a heat source when loomed. I'd keep it 5-6 inches if not. If you do fuse it, you can start with the 250. The most that can ever be drawn from this wire is what your alternator can produce, which is rated at 250 amperes. Most alts don't produce what they're rated for in real-world (heat, RPM speed, wire resistance, electrical demand all play a factor). Worse case, the fuse slowly burns and pops and then you buy a 300-350 fuse. [/QUOTE]
