[QUOTE="helotaxi, post: 7080082, member: 550915"] Depends on where the fuse is placed. If the fuse isolates the battery from the rest of the circuit and every ground strap from the engine is fused as well, then fuses on the negative wire would provide short circuit protection. It would be a silly way to go about it and would cost you every circuit in the car as already mentioned, but it would still work. The car chassis is only a ground plane when it is connected to the battery negative terminal Sever that connection and the chassis is irrelevant. Fusing the battery negative would in theory provide protection. In practice it would be effectively impossible to implement as the sole means of protection for all the car wiring since the fuse would have to fulfill the mutually exclusive goals of being small enough to protect the smallest wire while large enough to allow all circuits to operate correctly. It would also leave you subject to being wholly screwed if you manage to blow the fuse and don't have a spare handy. [/QUOTE]
