No. That is why I got stopped by the police. I was tooling down the
country road in pitch black with no headlight. I was taking it on faith
that there were no obstacles, as the cars ahead of me were doing OK.

I forgot that I have the shop manual. You are right about the
fuses--nothing in common. But in reviewing the schematic, I did discover
something interesting ... the starter button also appears to black out the
headlight while cranking (based on the schematic--I've never noticed that
this does or does not happen on the bike). But in any case, if the
connector involved were to come loose (several conductors), it looks like
the headlight would not work and the starter motor wouldn't crank (no juice
to the solenoid). Pending more information, the starter switch and
surrounding wiring is my prime suspect.
So, what I'll do in order is:
a)Check all the fuses (just in case two blew or something like this).
b)Locate the connector from the starter switch and look for anomalies there.
c)Trace the headlamp problem and see where it leads (it would probably also
lead to the starter problem).
I actually have a BSEE and an MSEE and truthfully, I hate wires. I also
hate the wiring diagram from Honda which is a rat's nest. What screws it up
is that Honda has to show the connectors as well, which leads to a rat's
nest layout.
Looks like me an my voltmeter may be spending some quality time together
next week.

Night, and even though I have a flashlight, aren't even sure where the fuses
are. Will be finding out now, though.
