I put a switch on the field wire. That way when accelerating I switch off the alternator and when decelerating I turn it back on. The only issue is to make sure the switch is on when my wife drives the truck. Otherwise I get the dead battery call. I like the idea of making it automatic. I also agree you don't need any relay on the output leave it alone.
