Correct, if you are getting continuity to ground you have a short. I would also check for high resistance from the horn, brake wires to the fuse block just in case the wire is burned or cut. Sent via BlackBerry by AT&T

There is no power to the brake lights, horn or the turn signals. The running lights work as they should. I replaced the left handle bar controls, the fuse block, tried to trace the green and white wire but my electrical skills are less than fundamental. I would think you are right - that the white and green is grounded somewhere. I should be able to trace that by using an ohm meter shouldn't I? Any ground from the white and green should show no resistance when I connect to ground from the w/g, Graham On Jan 24, 2012, at 10:44 PM, Allen Thomas wrote: > No problem, I hope it is of some help. > > On Tue, Jan 24, 2012 at 10:34 PM, Graham Rogers > <[email protected]> wrote: >> thanks Allen, I'll check all this out tomorrow, Graham >> >> >> On Jan 24, 2012, at 10:30 PM, Allen Thomas wrote: >> >>> Graham, I think I found the right wiring diagram here: >>> >>> http://www.cmsnl.com/classic-honda-fansite/honda_wiring_diagrams/ >>> CB650C.jpg >>> >>> So breaking this down into two different issues to make it easier >>> since it doesn't appear that both circuits are connected (almost). >>> >>> Brakes: >>> The green is ground, brown is tail light power, and Green Yellow is >>> brake light.
