Using drill the battery isolator is mounted on the fender well. Then the screws and the bracket that comes with the battery isolator are self-tapped . a length of four gauge battery cable run from the positive terminal of the first battery to the terminal on the battery isolator on the right hand side. The end of each side of the wire is stripped about half inch from the end and a terminal on to each end is crimped using a terminal crimper. The positive terminal from the first battery is connected to the terminal using a 3/8 inch ratchet and socket.
A 4 gauge battery cable run from the positive terminal of the second battery to the terminal on the battery isolator on the left hand side. The end of each side of the wire is striped about half inch from the end. A terminal on to each end is crimped using a terminal crimper. Then the positive terminal on the second battery is connected to the terminal on the isolator using a 3/8 inch ratchet and socket.
