Interesting comment.I know some Kawasaki ignitions have a strategically placed resistor so that the bike can’t be hot wired. If you know how to use a multimeter measure the resistance instead of voltage with a lead light
Most of the similar schematics I found show the ORANGE/YELLOW (dim) wire going to the ECU. One of the schematics I found said (theft) next to that wire.
I'll take a look. There's a cheap multimeter around here, somewhere. For sure, I've never used it.
