Title: Re-wiring diagram of my CB550 K3 is that correct?
Post by: thomaspigeon on August 24, 2020, 10:28:10 PM

Hello everyone,

I’m rebuilding a CB550 K3 that I bought disassembled. I’m rebuilding it slowly and I’ve just done the re-wiring for the ignition and charging system. Before I start it and maybe fry something, I wanted to submit this diagram. I don’t want to see this old lady becoming a bbq  ;)

Let me know what you think.
Best

Tom

Not correct. Kill switch should have black wire. But why not consult: Shop Manual Honda CB500-550? Wiring diagrams CB550K3 models are in: p. 182-5. https://redirect.viglink.com/?format=go&jsonp=vglnk_159833613188413&key=491a26ef78dc0f6ae357dff10ef22588&libId=ke9jxh9h01000nzd000DL91hvqugj&loc=http%3A%2F%2Fforums.sohc4.net%2Findex.php%3Ftopic%3D17788.0&v=1&opt=true&out=https%3A%2F%2Fwww.4shared.com%2Fweb%2FdirectDownload%2FD9yAdyN5ca%2FKcO7Iw3I.cf0de81ba0f43f0df073fa2836db5cdf&ref=http%3A%2F%2Fforums.sohc4.net%2Findex.php%3Fboard%3D2.0&title=

Thanks for you reply deltarider. I know it's black but for some reasons I've put it in orange. I can't follow a regular wiring diagram as I bypassed a lot of things like the starting motor safety unit, I also changed the reg and rec for a single reg/rec unit and I also changed the points for an electronic ignition system. That's why I ask for some external point of view about what I've done as it's not really standard
