He could he could try testing CDI box gray wire see it show the same volt and check the value to be sure that at lease good base on this chart.
Nah, any problems with neutral, clutch, side-stand switches, or relay and starter won't crank at all. He's already tested and swapped in 3x perfectly good pickup-coils. No need to shotgun pile of new parts to replace perfectly working parts because nothing will change.

Problem has already been identified, too much voltage on grey wire going into Ignitor. Now just matter of tracking down cause of that high-voltage.

Additional test some people have done is cut grey wire and attach 9v battery directly to section going to Ignitor (9v battery ground to chassis-ground). This test will confirm for sure that too much voltage on grey wire from ignition-switch is problem. But... for same amount of effort, he can just restore to factory wiring and rectify problem permanently.
