[QUOTE="DidUHearThat?, post: 4689191, member: 594758"] I'm assuming the 770 CCA battery is in the front stock location and the Batcap is in the rear? You don't need 2 fuses between the alt and the main battery, one near the main battery is fine. You DO NEED, 2 fuses between the main battery and the rear battery. Otherwise if the wire going thru the fire wall gets cut and shorts that wire will glow red hot, burn thru everything, explode both batteries and set your car on fire. I just did installed a second battery and I used an isolator as well to prevent the batteries from draining each other. After the second battery, there should be a fuse on the wire, near the battery for each wire that leaves the battery to the amps. Not near the amps. Othewise the wire from the battery to the fuse is unprotected. You could run short wire to a fused distro block instead of buying two seperate fuses. Any positive wire from or to the batteries must be fused within 12 inches of the battery. From battery to battery that means there are two fuses inline. You don't need a fuse near the alternator, just the battery. [/QUOTE]
