Question about 1995 Honda CB 750 Nighthawk

1 Answer

Push starter button, headlight dims, no starter motor, etc.

95 Honda Nighthawk 750: Have been working on the bike for a few weeks now and one of the projects was the blinkers. So, after a little research, I found out that the LEDs I was trying to get to work would not because they do not have enough of a draw to properly trip the flasher relay. The problem I have is during this process of testing blinkers; on, off, left, right, on, off, etc. - I somehow don't have a starter anymore. Push the starter switch, light dims, and that's it. When I know for a fact it was working prior, even with no blinkers. I think I may have a bad ground or something shorting because with left blinker on and front blinker wires caped and not touching eachother or frame, both rear blinkers blink and no indicator light, and right blinker switch: only the right blinks and with indicator bulb.. (This is with the stock configuration with no front blinkers, no LEDs involved). Any thoughts on where the problem could be? The only wiring I touched was the blinker leads and grounds, so I'm a little confused and honestly getting kind of frustrated that I can't get this thing finished. The battery is brandnew and this bike has never had a starter issue until I messed with the blinkers. Thanks for whatever advice you can give, John K.

    So, I have an update:

  • kozkoz May 10, 2014

    I went through all the starter wiring from battery to ground and eventually found a fuse that was not engaged all the way. The fuse box houses different slide-on connectors and one side had been pushed almost out, so held it tight in and replace the fuse, starts up no problem.

    My text issue is the headlight / blinker bs. For some reason I don't have my headlight running any longer with battery engaged. I took of the headlight-bulb bezel and tested the buld with the lead/ground for the blinkers and both filaments are good. I can't figure out where the bad spot is as I've literally looked every inch over. (With Stock blinkers...), left side works perfect, indicator light flashes with them. Right side on the other hand, flashes all 4 blnkers instead of the F/R-R ones. I have a diagram for the wiring and cannot figure out where the heck the problem is. Orginal flasher relay is in there, same thing happens with the electronic one. Checked the headlight fuse, and in the fuse box, there is only one slide-on connecter that the fuse engages, not two. I could find a missing connector but I've never noticed if there were 2 or only one. Thoughts?

    That's great! Glade to here you found the problem. Sometimes it's the less obvious and simple things that cause the problem....

Yes, LED turn signal lights require a flasher rated for LED's. They are available in auto parts stores.
As far as the now start goes, double check all wiring, making sure all the positives and all the negatives are correct. Check the ground wire from the battery. Make sure the connections are tight.

    Thank's for the response. I have since bought an electronic flasher with a harness for the flasher side but have yet to get it to work properly, moreso In focus of the starter issue rather than a problem in the flasher setup, etc. Only have a day off every 6 so it's hard to get it. Replaced the clutch in my s10 1-day a week for 4 weeks this same way lol. I'll post with any updates or resolutions but if people still have ideas, feel free to throw them out.

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

1996 honda 750 nighthawk headlight doesn't work fuse is ok ,bulb is ok


Hi, Anonymous if your headlight is not working, only one beam works, keeps burning out, blinking, dim or surges from bright to dim to bright the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your head light bulb socket ground wire for a clean tight connection, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn down solder contacts or loose fit of the bulb base in the socket due to vibration.
3. Worn, chafed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/lo beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty headlight relay.
9. Faulty wiring between battery positive and headlight bulb socket.
10. Weak charging alternator/generator/lighting coil
11. Faulty voltage regulator/rectifier ground or overcharging.

I hooked up my working car battery to my bike to try and start the bike .. yes the bike battery is dead... ok i hold the clutch in, kick stand is up... my indicator lights are on... my headlights are...


Start by checking the starter button. It is a two function switch. It turns the headlight off and activates the solenoid. Try cleaning it , some disassembly may be required. If it is broken you may have to change the right switch assembly to fix the problem. Your dealing with some type of shorting or grounding in the switch, probably caused by corrosion from sitting in the weather outside.
