very suddenly lost all spark to number 1 and 2 cylinders, the two farthest away from the flywheel. i have not done any diagnostics yet, first i was going to change out 1 and 2 coils with 3 and 4, known to be good. but i have my doubts that i lost two coils at the exact same time going down the water. my question is, after i verify the coils, is there a way to test the switch box and trigger assemblies simply using a test light and digital multi-meter? thanks.
