My take on how that works: The anti restart is a 4 terminal relay, pos and neg, and a switched circuit. The relay is normally closed when no power is going to it. It is in the start circuit along with the key switch, neutral switch, and starter relay. The anti start relay only operates when the voltage going to it gets above approx. 13 volts. Key on, white wire (although it may be black/red wire) should be energized and everything should be getting power, anti start relay, dash, ignition, lights. Since the voltage is below 13 the relay has the start circuit still closed and ready to go. Turn key and start engine, voltage rises above 13 and relay coil has enough power now to pull the contacts open and making the start circuit inoperable. The coil in the anti start relay stays energized the whole time the motor is running and voltage is above 13.
