    I have twin 2007 F250's, does the charging lead from the alternators charge the battery via a seperate wire or does it charge through the starting wire like my older twin 2002 F225's? Can anybody send me the wiring or rigging diagrams to connect the engine wiring to the boat?

    The alternator charges by way of engine battery cables. The engines does have a battery isolator built into it and can charge a second battery with a optional battery lead part number 69J-81949-01-00.

      Could you send me the wiring/installation instructions for the accessory charging lead?

        It just plugs into the red wire at regulator( should find it laying in engine pan) and connects to positive terminal of battery.

          Does this engine also have a battery isolator built in?
          If so, where will I find the connection point?
          I plan to charge a second battery for the *****ing motor.

          Thank you.

            No the 2002 115 does not have isolator would have to install an external battery isolator for that motor.
