Ignition switch issues
« on: October 31, 2019, 04:49:43 pm »
Hey all,

recently bought a project 78 cb550k. Bike was in decent shape but the wiring job done on this thing was a mess. Long story short, before i took it apart I confirmed everything was working, came to me firing on 3 cylinders and wouldnt idle. Fixed some wiring, changed the plugs and was good to go. I began to take apart the harness and ran into an issue. I now only have the ignition switch, starter magnetic relay and alternator wired in. Every time i turn the key, the main 15A fuse blows. There definitely arent any live wires grounding somewhere (hence why I have so little wired up, just want this thing to turn key~!). I've attached a diagram of what I have wired. The ignition switch look aftermarket, its got a crank position like a car ignition. It DID work before i took everything apart so im 99% sure its some missing or incorrect wiring to the ignition switch on my part. Any one see whats wrong with my ig switch wiring?

Thanks,

Happy to join the club!
