Ignition problem

<< < (2/9) > >>

You would have had to raffle about in the “birds nest” of wire connections in the headlight whilst trying to sort out your indicators, maybe disturbed kill switch connections? Bit bewildering sometimes. With ignition on and kill switch on is there power at coils/electronic ignition? Good luck!

Sorry, my fault. I just messed around with those wires when i took the photo. The black ignition wire (braided black) is connected to the 2 black/white ones from the coils to make the kill switch work. Iv tried connecting it strait to a black wire but still no go.

I havent got the tools to check that. Looks like i may have to get it.

I'll keep checking for faulty/loose connections. Im just afraid that something bad happend with the coils.

Btw, no take on what the lose black wire on the original picture is for?

Regarding the kill switch, as far as i can tell, that is bypassed if the ignition wire is connected straight to a power on black wire. Is that correct?

Magnus, can you be a bit more specific about your model bike (area code). It's not unusual to find a 'blind' black wire on the CB500. Mine has one too. This has to do with differences in wiring scheme in various markets, like the arrangement for the horn. Where have you bought your new wiring harnass? Do you have the correct wiring diagram for your model?
Best way to identify your model is to compare the engine- and framenumber of yours with those listed in the first 4 pages of the various parts lists. They are all here: http://www.honda4fun.com/materiale-documentazione-tecnica/parts-list/parts-list-cb500
