Just because pro-mechanic can use Power Probe, doesn't mean that
you can. An understanding of circuit from wiring-diagram is required first.

Using a Power Probe the 3 wire switch reads grounds. I can apply a 12v to any of the wires. When I do, the headlight turns on. I can pull the Probe away and the the light stays on. When I turn off the ignition, then on again, I get nothing again. I do have a schematic from Cyclepedia. I don't know enough to figure this one out.
Any suggestions?

You criticize what you don’t understand and run off topic. Your unwanted analysis of the techniques in using the Power Probe III are off topic, not helpful, pedantic and self indulgent at my expense. Why not explain the circuit in the first place? All the off thread writing is your way of creating obfuscation, no more, no less.

At least
four people explained to you how headlight circuit works.

After the bike is running if the kill switch is pressed the light will stay on, but if you turn the ignition off and then on again the bike will need to be started before the headlight will come back on. At least that's my limited understanding of it. Unsure if you can just touch the starter quick to turn the headlight circuit on.

My 2015 Honda Grom's headlight doesn't turn on until I fire the engine. Same with my 2006 Ducati.

You refused to believe them, so I went backwards further to show that your assumptions, which you believed as absolute truth, was holding you back, wasting time and not arriving at solution. Not just in this case, I'm sure it will hinder you in future as well.
