One wire alternator. Cut the power kills everything. I have a 100amp GM alternater . But my friend has a chrysler alternator converted to a one wire. No extra wires relays or solinoids. Just one wire coming from any power source thats interupted by the disconnect. Doesn't get any simpler. My battery cable coming from the trunk goes to a single stud bulkhead post on the frame next to the motor. That acts as my pos. battery post under the hood. From there I ran a 7 Inch wire to the alternator and that is all you need .
