Ignition problem
mickwinf:
yes the spare black wire is normal, sometimes used as a horn feed as Deltarider says in some markets.

Thx for the link.
Seems the engine and frame is K2?
Engine: CB500E - 2152850
Frame: CB500 2064103
The new main harness is a copy of the original harness that came with the bike. Iv checked and the black wire is present on the old harness to. Looking back it feels like i cant even be sure the old harness is the correct one for the bike. When i bought it it was just half complete and ALOT of parts was missing. Whos to say he didnt replaced the harness from another bike at some point (i doubt it though). Need to point out that it is not possible to ask the last owner since he sadly passed away.
In all honesty, i cant swear the new harness is the correct one but it looks like it and maby im just starting to get paranoid :).
One thing this bike tought me is that next time around i will stay clear of any project not 100% complete. A new handlebar is fine but most other stuff is a pain in the a** to find. Especially when it has to be Year/model specific. The more i look into it it seems the bike is a miss mash of K1 and K2. Partly because of the parts i was able to find (like the fuel tank that is from a K1)
On the positive side, i did have it working the other day so thats allways something. If i get it running again i will hold of with the turn signals until after first test run on the road.

Ok, thank you. One less thing in the equation is allways good.
deltarider:
If your model has only one fuse and two grease nipples for the swingarm (one on each side), I'd say yours is a K1, as sold in Europe. At the end of the Owner's Manual there are 4 different wire diagrams. For you that is probably the -ED type. Unless your bike has been imported from elsewhere. http://www.honda4fun.com/pdf_libretti/500/CB500_k1/CB500_K1_4.pdf
Seabeowner:
Yes, if it's a bike that was registered in UK new, it is a K1. All K2s are imports (USA usually). The numbering system on SOHC4.net is for US models.
Post a pic.
