Battery Relocation Fuse
You started by saying 250A is what you need. What were you powering with that? I ask because on my Hombre swap, I threw the battery under the bed and sent two (2) 2 gauge wires to the front: one straight to the starter, the other through a 150A fuse to a post that distributes to the fuse box and the alternator. My voltage is a steady and happy 14V at any given time when heat soaked.
I never liked that my starter wire isn't fused, and I wouldn't mind throwing a block in if it would handle the amperage. So, if I had a dedicated 2ga wire to the starter, what size fuse could I put in there?
I had a little incident last year, my starter wire was laying on the header, burnt the wire and went to ground. Blew the 200 amp fuse.
If you don't want to fuse the negative side, I'd put both your wires on the same 150 amp fuse, And see if it holds.
Since you have the fuse on the positive side, I'd just break the starter wire and put it on the same 150 amp fuse and see if it holds. Probably will.
