I have a 84 Honda NightHawk 700s and I turn on my bike and the headlight does not turn on unless I hit the hi beam switch, what could be wrong in the wiring?


Hi, Anonymous if your headlight is not working the first thing to check is the headlight bulb for damaged filaments then check your light circuit fuse, that being said the usual suspects are:
1. Faulty ground or power supply to headlight bulb socket.
2. Faulty hi/lo beam switch.
3. Faulty ignition switch.
4. Fuse is good but no continuity on both sides.
5. Faulty wiring between battery positive and headlight bulb socket.

Hi l got a 84 nighthawk 700sc cant get the clutch to bleed l just put in a new kit in the master cylinder.


Loosen the banjo bolt on the clutch master cylinder, Put a plastic sheet and a rag under the banjo, pump the lever a couple of times till DOT 3/4 brake fluid starts pouring out past the sealing washers. You have now gotten the air out of the master cylinder. Tighten the banjo bolt, bleeding the lines should now be easy.

Hi and welcome to FixYa,

Check / replace the diode that connects the clutch switch and neutral switch. The diode normally would have green/red and light green/red wires.

Good luck and thank you for asking FixYa.
