Motorcycle Repair: 1981 honda 650 cb custom, honda 650, starter button

Question
headlight went out as i was riding it. replaced the bulb h4 and still will not come on, its not getting power. is there a possible fuse and if so where it might be located?

Answer
Vincent,

-the fuses are usually between the handlebars
or if not there look under the left side cover.

-The power to the headlight comes from the fuse
to the handlebar starter button (red/black wire)
The problem is usually in this button assy.
(The starter button normally turns off the headlight when starting.)

-the power then goes from the starter button
to the headlight dimmer switch on a blue/white
wire. From here the power goes to headlight, high/low beam.
