Question about 1992 Honda CB 750 Nighthawk
Posted by Anonymous on
Hi, Anonymous before testing any electrical component in the Starting System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand, clutch, neutral safety switch.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter motor or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. Faulty ignition relay.
14. The electric starter is working but starter clutch has failed.
15. Check for engine trouble codes.

Look around the engine oil drain plug and fill area and see if there is an electric sending unit( small plug with a prong for a wire) that is screwed into the engine if so check to see if its unplugged / could be a low oil cut off switch that kills all power to the ignition if the oil is to low ( or the wire is unplugged)

follow your accel cable to the carb. move the throttle till you see where the linkage moves. look around the linkage to see what it hits on at no throttle. that will be your idle screw

Hi and welcome to FixYa,
Your decribed problem could either be a neutral switch about to fail (least likely) or a loose grounding issue (most likely). This switch must read 0 ohms to ground when in neutral and infinity (no reading) when in any gear.
Good luck and thank you for asking FixYa.
