No spark can be attributed to two components; The stator or the trigger assembly. Even if you had a diagram (available online @ Mercury), you will still need a test harness,a DVA adapter and a meter to measure the resistance of the CDM's (capacitor discharge module) ,stator and trigger assembly. Best case fix would be the trigger, most expensive would be the stator. If you remove the flywheel, and inspect the stator, you can inspect the the coils that are coated with a white epoxy, and if one or more are bad, they sometimes leak a black resin, indicating the coil(s) have been shorted and no longer provide voltage for spark.
