I'd say your Haynes diagram is Wrong ..
85-87 diagram comes from honda shop repair manual I scanned and colorized wire runs..
Appears the 2nd gen rebel has an 8 wire pin-out where the 85-87 is 9 wires..
additional Green harness wire of 1st gen switch provides ground to starter solenoid via clutch lever switch, wiring diagram indicates it doesn't interact with any internal switch contacts..
never had a problem with switches other than contacts needing to be cleaned.. Thus I have only been into junction box to add diodes for LED turn signals.
on another note @kryton
is correct, grounding kill switch circuit kills the cdi output.. during run that circuit should be open..
as a side note the 1st gen ignition switch has a third "Park" position that grounds the same Bl/W cdi wire yet energizes tail light.. 2nd gen Rebel Ignition switch has no P park position, on off that's it.
makes finding replacement 1st gen 6 wire Ign switch a pain.. after 30+ years the plastic housing becomes brittle, known for breaking..
as a final P.P.S. No the Rebel has no headlight off position.. Headlight circuit is disengaged when start button pressed so it isn't drawing power while starter is being energized..
