OK. the haz/horn fuse is hot all the time, it gets it power through a fusable link. The wire from the fuse (green/orange) splits into two (green/orange and green/white). Green/white feeds the horn directly (+) and the horn is switched by ground at the steering wheel. The green/orange wire goes to the Hazard switch. When the switch is open (off) then your turn signals get power from an ignition source. Try these two things and see what you get on your anmeter. Disconnect the horn completely, check your results. If that doesn't do anything reconnect them and try this. Open the shroud around your steering wheel, find the hazard switch and disconnect the Green/orange wire, then check your anmeter. BE CAREFUL these wires are hot (horn and hazard) so disconnect the (-) battery before disconnecting and reconnecting any wires, and dont touch them at any time to metal.

Also check this wiring and make sure it has not been tapped for power (maybe for a stereo, CB, accessories (like a make-up mirror <img src="/forums/images/graemlins/nana.gif" alt="" />) ), some people tap this circuit cause its hot all the time.

The hazards are not part of your light circuit unless the hazard switch is on, the switch is bad, or crossed wires.
