[QUOTE="gbody805, post: 6691816, member: 558997"] First no fuse required for the ground, always fuse the amps. Second: Ok let us say for a minute. You have a front and rear battery. You run the power cable from the front to the rear. Your cable is ran thru the firewall and for some reason (let us say just for instance) the grommet fails,melts, turns to dust whatever. The power cable grounds to the firewall.[IMG]//content.invisioncic.com/y282845/emoticons/scared.gif.f134e57c6c93ccd0f15aa5ac32c7d4a0.gif[/IMG] The section of cable from the firewall to the front battery has a fuse and said fuse opens from the huge current draw. Cool everything up front is safe. Now lets see what happens to the rear section that has no fuse.[IMG]//content.invisioncic.com/y282845/emoticons/popcorn.gif.32dd9e22fd77e77bc3c907062768fcd2.gif[/IMG] The least that you can hope to happen is the wire is strong enough to take the huge power draw that a fully charged battery has to offer, and the worst you get is a melted wire that discolors the carpet in a neat line that runs from the front to the back. The worst case:omg: The battery unloads, the cable starts slow with just melting the outer case, then turns bright glowing red as it starts to melt! But wait a 1/0 guage wire will stay glowing red just long enough to start melting the carpet. If you're really lucky it will have a nice light show complete with flames [IMG]//content.invisioncic.com/y282845/emoticons/awesome.gif.4430a219d9aaaa6cadc75e9290979dfb.gif[/IMG][IMG]//content.invisioncic.com/y282845/emoticons/handclap.gif.0c301076f534e244f0460706894f19e0.gif[/IMG] Just because you really didn't want to have just a little $15-$25 protection like a fuse protecting that pest of a rear cable. It's your ride you do what you think is best. Oh wait that's right the net guy said it would be alright [IMG]//content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif[/IMG] My bad. I'll just move along looks like everything is alright in here.[IMG]//content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif[/IMG] [/QUOTE]
