Topic: wiring on cb500 four,ignition switch button,electric starter button.

Hello,i am a new member trying to get my cb500 four barn find running.Can any of you guys advise me on the wiring of the ignition switch button and the electric starter button.In my Haynes manual wiring diagram colour key,it omits a black/red wire,it also omits a brown/blue wire.Both these wires are hanging loose in headlamp shell!.They are from control for the above bunch wires.I have looked at another wiring diagram on internet and the black/red wire goes to run/stop switch.I cannot find the brown/blue wire in the Haynes or the other diagram..Any advice on where these wires should go would be really welcome.

Thats because the rh switch you have is neither Honda nor for a 500.
If you are good with a multimeter and can tell me what colour wires go where in the switch unit i may be able to help

Brown/Blue is the Turn Signal Buzzer. It connects to the LH side control. Probably a PO removed the buzzer and left the end dangling.

The later US model Hondas with the full-time head-lights had a black/red wire from the switch that fed the headlight until the starter button was pressed, when the light would shut off and 12V would go to the starter solenoid on the yellow/red wire.

Yes Scotty but the early ones grounded through the bars so if you connect a later switch to an early bike you put +ve 12v to both sides of the solenoid and that wont work. You can modify things to work but you need to know what wires go where in the switch to work it out, to make it worse some of the aftermarket switches use the same colours as Honda but connect to different bits so if you wire colour to colour all sorts of wierdness happens.

To the OP  please put up a pic of the switch as well
