Question about 1993 Honda CB 750 Nighthawk

1 Answer

1993 Honda CB 750 Nighthawk will not turn over

I stopped for gas. Turned the key & NOTHING. I switched the 2 10 amp fuses, & wound up pushing my `91 750 home. What should I check next? I just got this 1991 750 Nighthawk, & had no trouble before. No lights, no noise, no nothing. I`ll try changing the 30 amp fuse today. The battery cables are tight. I might pull the ignition out & check for loose wires. Any suggestions will be greatly appreciated since I`ve only driven it home, & to the gas station so far. It seems like a great bike, & all lights worked perfectly before.

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 have failed 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 at this starter relay close, there is a fuse under a black plastic cover, check this fuse for being burnt. Next check the kick stand safety switch, make sure it is in the bracket, tight no loose wires. Next is the clutch safety switch. And last is a neutral safety switch. Here is a manual for you to download. Hope this helps Fix Ya. up. >>>Hondamanual

My 82 750 Nighthawk and the headlight does not work before and after it starts


First, test for voltage at the plug that attaches to the headlight, if you have voltage at each terminal when set to it's respective hi or low position it could only be your headlight. If you don't have voltage then you need to work back from the wire to the switch and etc etc

My 1993 Honda Knighthawk wont run.


The slow circuit of your carbs are dirty. you need to remove the carbs from the bike and thoroughly clean the internal passageways and jets. that should solve the problem. Always drain your carbs for storage and use fresh gas when you start up after long storage.

My headlight is inop on my 1993 750 nighthawk, I suspect the problem to have something to due with the ignition system. I replaced the fuse and headlight and checked the high/low beam switch.


The two most likely culprits are the ignition switch and the starter button. The starter button, in the right handlebar switch assembly, performs two functions: cranks the electric starter - and, at the same time, turns off the headlight. Sometimes the electrical contacts inside the starter button burn out and fail to reconnect the headlight circuit when the button is released.
You can easily determine which one is the problem by simply checking for battery voltage at the headlight fuse. No voltage means the likely cause is the ignition switch. Also inspect the large plug on the bottom of the ignition switch. Sometimes the individual connectors will corrode, melt, or push themselves out of the plastic housing.
If there's voltage at the headlight fuse, then plan on replacing the right handlebar switch assembly.

1983 Honda Nighthawk 650 stopped starting


Sounds like the starter solenoid went bad. Turn the key on, Make sure it in N. Take a screwdriver and jump the terminals on the solenoid and see if it turns the starter over and starts the bike. If it does then the solenoid needs replaced.
