Dont forget that there will be a voltage drop if anything is taking power e.g. coils, neutral/oil light etc. There should not be  that much of a drop on the red line with no load and with your results taken as is

That means the contacts in the switch are high resistance.
Option 1 fill it full of wd40 and work it a lot and retest

Option 2 if 1 does not work take switch apart and manually clean contacts and retest

Option 3  if neither 1 nor 2 work new switch

1v is a bit much of a loss through the wiring suggesting a bad connection somewhere. With the pos probe on the battery check voltage on the bat, earth lead at engine, engine cases to see if earth connection is good ( should be same voltage at all points) Then assuming ground checks out ok with neg on battery work from bat + to solenoid, fuse(s) both ends, ignition switch input, ignition switch output etc to see where voltage is being lost

Genuine Honda is best although even they can have errors, good standby would be Haynes

Not necessarily mate, reg/rec may not be working new or not or the wiring/connections may be dodgy, either is far more likely than a duff alternator. Only bad alternators/field coils i have ever seen duff in 35+ years were mechanically damaged

The black is a switched power and nearest place,electrically, to battery is at the ignition switch

Matters more with switches wether ac or dc as dc sparks heavier

You have to remember that Honda started with the airbox hanging on a piece of string and built everything else arround it, same as steering box on Landrover
