With the Sprint Car Crank Trigger system, the timing is first set at the magneto to ensure correct rotor phasing. Then, the pick-ups are switched and the timing is checked and adjusted again at the crank trigger pickup. This switch allows you to start the car and toggle between pick-ups, so the car only needs to be started once to get the timing dialled in. Also, by setting the generator slightly retarded over the crank trigger, the driver could switch pick-ups and have two timing settings.
