[QUOTE="Water Bear, post: 8864617, member: 673826"] It depends on exactly where your batteries are and how many you have and all that. You want your fuses close to the batteries, preferably within a foot or so. What you're trying to prevent is a situation where the wire gets damaged mid-run or disconnects at the load and becomes a short to ground against your frame. If the wire pops out of the battery then it won't be a risk unless it's tied to another live wire (for example the wires connecting parallel batteries). Basically you have to diagram your system out and put a fuse anywhere there's a power source or risk. That includes the line from alt to battery, for the same reason as above. If that line frays or fails, you have a battery line shorting to ground. [/QUOTE]
