No start - what to check

Ground it. I pull those when they go bad and just ground wire to bolt mounting of relay on fender. Just start in neutral, smartest thing to do. Try rebuilding it, its possible.

Same here I hate clutch safety switches.
Not too fond of neutral safety switches either.:D

But I grew up with the habit of 100% checking for neutral first with sticks, but not holding the clutch down and straining dry thrust bearing surfaces.
