Question about Honda CB 750 Nighthawk Motorcycles

1 Answer

Ignition switch My bike started fine in the morning. When I left work to go home though, there was no power and no lights were working and the horn didn't work either. I jiggled the key and got power back and made it home. The next morning when I tried to start it, the same thing happened. The only difference is that I couldn't get the power back at all and now the key comes out while in the run position.

Worn ignition barrel, or maybe the key is worn. Do you have a 2nd key try that 1. Maybe the key you are using has a slight bend in it.

SOURCE: 1998 Honda Goldwing will not start nothing.

Sort of sounds like a Twilight Zone kind of problem doesn't it. I would have the battery checked for an internal dead short. This is something that happens on odd occasions and can happen even to a new battery. Yea, the little lights will work ( they do not draw much juice ), but the starter motor draws a lot of juice and a shorted battery just ain't got it. Also check the wiring harness connections. One loose connection can cause bunches of trouble.

look under the seat and along the side panels for wear signs on the cable loom , Sounds like something important has grounded itself to the frame , hence the battery discharging and loss of ignition ,

When you reassembled the bike did you pinch any of the wiring harnesses? Trace the wiring through the bike and make sure everything has a solid connection between their respective power sources and activation switches. Alot of time bikes run wiring under the gas tanks so you need to make sure that you didnt cut anything when pputting it back on (if you removed the tank)

Sounds like a detached connector or a blow fuse. First open your user manual, locate the fuse holder and dbl check the fuse... You have two circuits, the On circuits, and the accessoiry (wich are not essential) seems that you lose the accessory...

SOURCE: lights, turn signals, horn don't work

Look for a bad ground connection inside the headlight shell (or possibly elsewhere). The other thing that all of the items you mention that are working intermittently have in common is the ignition switch. With the switch 'on', check for battery voltage at the fuses for the headlight, turn signals, horn, etc. No voltage at the fuses likely means a bad ignition switch.

Ignition switch on, bike runs, no running lights. Signals, horn, and brake light work.

If you think it might be the switch, you could squirt switch cleaner into the key slot and work it. Have you checked for fuses under the seat, tank or behind the headlight?

Why won't my lights work?

Have you checked the wiring to the lights. Sounds like you have a wire that has shorted to ground. Would also explain your battery drain. I'd check the wiring before the ignition switch since it is draining your battery with the switch in the off position.

Headlights not working, rpm gage not lighting up, neutrel light not coming on

Hi Anonymous, and the usual suspects are:
1.Ignition/Light Key Switch not in IGNITION position.
2.Engine Stop switch in the OFF position.
3.Discharged battery, loose or corroded connections (solenoid chatters).
4. Bank Angle Sensor tripped and Ignition/Light Key Switch not cycled to Off and then back to Ignition
5. Starter control circuit, relay or solenoid faulty.
6. Electric starter shaft pinion gear not engaging or over-running clutch slipping.

i think when you turned the ignition that was when the switch went, if its not been used for 12 years, the copper in the switch would of oxidized, you could try spraying some switch cleaner in the lock and turning the key back and forth and see if that sorts it other than that you would need to replace the switch.

Hi i drove to work and as i pulled up and put stand down the bike died and wouldnt start.i left it and the next day in the morn it wouldnt start still about 8 hrs later i finished work called the AA and 15...

I think the stand is the cause of the issue. Check the stand switch as if the bike is in gear or you have the clutch let out and the stand is down, it will not attempt to start.
Hope that helps.

The bike was running fine in the evening. Rode to work parked the bike took the key out. The battery was dead in the morning. Put the 10 amp charger on and the motor started to turn over with the key off!...

your starter button is malfunctioning. maybe some oxidation in the switch. when starter button is pressed in that can cause your other electrical stuff to not work.
