Topic: 1974 CB550 wiring diagram (simplified)

[iambleach]

Hello all! First time posting. I have been building a 1974 CB550 cafe racer for the last year and a half. I have not been able to find a nice cleaned up simple wiring diagram so I made my own. So, here it is. I have a Dyna electronic ignition instead of OEM points, and a regulator/rectifier combo. Other than those, everything else is original.
So heres my diagram. I hope someone else finds it helpful.

Calj737, I had the fuse between rectifier and battery but a buddy said to move it between battery and ignition. You think I need both or just switch where it is currently?

As far as the SSM unit. I still have no idea what that even is. I was following another simplified diagram for that.

So if I got rid of the starter, I don't need the SSM either?

Thank you for your help, and once I get a reply from ya, I'll post an updated diagram.

Thanks again. I figured you were saying to use two, I just wanted to clarify as I'm in my garage right now.

As far as that brown wire going to a black:
I had a custom tank/seat made with a tail light. The tail has a red ground, a red power to main light, and a black for the brake.

So the original g/y from the rear switch is now a tan wire.

Totally didn't think about how those were different than normal when posting my diagram. But thank you for the info.

Oh, and I forgot all about the mounting bolts and seal on the starter! Wish I read your reply before I found that out on my own!
