No spark

My question is this how does the trigger work for spark. I understand it has a center magnet separate from the cdi controller. But how can it reverse poles to collapse a capacitor if this center magnet is magnitised all the way around it. How does the trigger sense the change . I would have thought it would have pos and neg poles to charge and collapsed a capacitor in the cdi switch box. The stator test one side open the other side good around 750k.
 
A magnet passes in close proximity to a coil. Voltage is created and sent to the CDI assembly. The voltage causes a switch to close that then allows current stored in a capacitor to be discharged to the ignition coil. The current flow within the primary of the ignition coil induces a much higher voltage in the secondary coil. When the voltage reaches a certain value a spark will jump across the spark plug

Ok I know the (LS) low side coil is open circuit and it controls the idle to about 2000 rpm if I'm understanding the system. So if it's open I won't get any spark to either primary coil correct.
